Every callter (except kthread_bind) should use proper
set_cpus_allowed_ptr() APIs.

We plan to remove cpu_possible_map and cpu_present_map later and we
have proper init_cpu_possible() and init_cpu_present() APIs.
Therefore this patch rewrites platform_init_cpus and platform_prepare_cpus
by their APIs.

Both the BF548-EZKIT and the BF561-EZKIT use top boot flashes, so now
that Das U-Boot uses the last small sector for its environment, update
their nor layout in the kernel accordingly.

Turns out the documentation is wrong and doing "RAISE 1" does not result
in a software reset, only a core reset. So when the on-chip rom has a
functioning reset helper, use it.

Since the value of these MMRs aren't changing, store the value in a local
variable and work off of that. This avoids multiple MMR reads which are
implicitly forced by the volatile markings.

The BF537 SIC combines the gpio port H mask A interrupts with the
emac rx interrupt, so we need to demux this in software.
It also combines the gpio port H mask B and the emac tx interrupts,
and the watchdog and port F mask B interrupts, but since we don't
support mask B yet, just add the defines for now.

The search logic in the gpio demux walks all possible gpio blocks starting
at the specified pin. The trouble on bf537 parts when we demux the port
F and port G mask A interrupts is that we also demux port H mask A ints.
Most of the time this isn't an issue as people don't usually use port H,
but might as well avoid it when possible.

The SIC interrupt line muxing that the bf537 does is specific to this
CPU (thankfully), so rip it out of the common code and move it to a
bf537-specific file. This tidies up the common code significantly.

After some cache setup reordering changesets, the blackfin_cpudata init
was left behind. While cpu0's data was correct, cpu1's data was not.
Not that big of a deal as these are only used in the cpuinfo output, but
should still be fixed. So move the setup of these fields to the common
cache setup function to avoid this happening again in the future.

Since the on-chip L1 regions are not cacheable, there is no point in
trying to flush/invalidate them. Plus, older Blackfin parts like to
trigger an exception (like BF533-0.3).

renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.
mackerel board has 2 USB ports.
But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.
We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.

The Core Standby mode is the lightest sh7372-specific

The low level portion of this code is based on the
TI OMAP sleep code in sleep34xx.S, thanks to them.

This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and
supplies 3 IRQ resources for each SDHI block.
Some blocks have a 4th IRQ, but this is used for DRM feathres
that I do not have access tot he documentation for and are almost
certainly tainted by licensing issues. So the 4th IRQ is not
hooked-up even if it exists.

Update the sh7372 clock code to set the RT side
set of MSTP bits to a fixed disabled state.
The sh7372 SoC contains two sets of MSTP bits,
one for the ARM (SYS) side, and one for the
SH4AL-DSP (RT) side. The actual clock associated
with the MSTP bit will only be stopped when both
sides have set the MSTP bit to disabled mode.
Some MSTP bits are enabled by default after
hardware reset, so this patch adjusts the code
to disable all MSTP bits associated with the RT
side to allow the SYS side to have full control.
