Less code ftw.
This converts all drivers except the tinydrm helper module. That one
needs more work, since it gets the THIS_MODULE reference from
tinydrm.ko instead of the actual driver module like it should.
Probably needs a similar trick like I used here with generating the
entire struct with a macro.

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.

Core code already makes drm_driver.get_vblank_counter hook optional by
letting drm_vblank_no_hw_counter be the default implementation for the
function hook. So the drm_vblank_no_hw_counter assignment in the driver
code becomes redundant and can be removed now.

Noticed that everyone duplicates the same logic here and we could safe
a few lines per driver. Yay for lots of drivers to make such tiny
refactors worth-while!

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Several DRM drivers print the same initialization message right after
drm_dev_register, so move that to common code. The exception is i915,
which uses its own register handle, so let it keep its own message.
Notice that this was tested only with Exynos, but looks simple enough
for the other drivers.

Instead of linking encoders and bridges in every driver (and getting it
wrong half of the time, as many drivers forget to set the drm_bridge
encoder pointer), do so in core code. The drm_bridge_attach() function
needs the encoder and optional previous bridge to perform that task,
update all the callers.

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.
Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.
Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.
There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

It's deprecated and only should be used by drivers which still use
drm_platform_init, not by anyone else.
And indeed it's entirely unused and can be nuked.
This required a bit more fudging, but I guess kirin_dc_ops really
wants to operate on the platform_device, not something else. Also
bonus points for implementing abstraction, and then storing the vfunc
in a global variable.
v2: Don't break the build soooo badly :(
Note that the cleanup function is a bit confused: ade_data was never
set as drvdata, and calling drm_crtc_cleanup directly is a bug - this
is called indirectly through drm_mode_config_cleanup, which calls into
crtc->destroy, which already has the call to drm_crtc_cleanup. Which
means we can just nuke it.
Note this is the 2nd attempt after the first one failed and had to be
reverted again in

Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

The function's behaviour was changed in 90844f00049e, without changing
its signature, causing people to keep using it the old way without
realising they were now leaking memory.
Rob Clark also noticed it was also allocating GFP_KERNEL memory in
atomic contexts, breaking them.
Instead of having to allocate GFP_ATOMIC memory and fixing the callers
to make them cleanup the memory afterwards, let's change the function's
signature by having the caller take care of the memory and passing it to
the function.
The new parameter is a single-field struct in order to enforce the size
of its buffer and help callers to correctly manage their memory.

Since commit 4984979b9b90 ("drm/irq: simplify irq checks in
drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only
required for drivers that have an IRQ handler managed by the DRM core.
Some drivers, armada, etnaviv, kirin and sti, set this flag without
.irq_handler setup in drm_driver. These drivers manage IRQ handler
by themselves and the flag DRIVER_HAVE_IRQ makes no sense there.
Drop the flag for these drivers to avoid confusion.

We already have a fallback in place to fill out the unique from
dev->unique, which is set to something reasonable in drm_dev_alloc.
Which means we only need to have a special set_busid for pci devices,
to be able to care the backwards compat code for drm 1.1 around, which
libdrm still needs.
While developing and testing this patch things blew up in really
interesting ways, and the code is rather confusing in naming things
between the kernel code, ioctl #defines and libdrm. For the next brave
dragon slayer, document all this madness properly in the userspace
interface section of gpu.tmpl.
v2: Make drm_dev_set_unique static and update kerneldoc.

Up to now, the recommendation was for drivers to call drm_dev_register()
followed by drm_connector_register_all(). Now that
drm_connector_register() is safe against multiple invocations, we can
move drm_connector_register_all() to drm_dev_register() and not suffer
from any backwards compatibility issues with drivers not following the
more rigorous init ordering.

This patch fixed the bellow no DRM_INFO is printed issue:
if (!delay_count)
DRM_INFO("phylock and phystopstateclklane is not ready.\n");
There will some printed issues with above info, under certain
circumstances:
If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.
Also if ((BIT(0) | BIT(2)) & val) is true at the last possible
loop round, break happens, but now delay_count is already zero
( because of earlier delay_count-- ) and DRM_INFO is erroneously
printed.
