Fix device delete child function.
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

r307091, r307092, r307093, r307095, r307098,
r307115:
r307067:
Make intc driver compatible with upstream DTS
- Fix compatibility strings
- Properly decode upstream's two-cell interrupt specs. Our home-made dts
does not have two-cell interrupts so no need to preserve backward
compatibility
r307068:
Make Rapsberry Pi watchdog driver compatible with upstream DTS
- Fix compatibility strings
- Compensate the difference in base address for our custom DTS and
upstream one (for backward compatibility)
r307087:
Make sure intc is attached before interrupt consumers
If pass order is not specified devices are attached in the order they are
defined in dts. Some interrupt consumers may be defined before intc. Also
make sure intc interrupt-parent local_intc is attached before intc itself.
r307088:
Add compatible strings used in upstream dts files
r307089:
Make framebuffer driver compatible with upstream DT
- Add compatibility string
- Add simplebus as possible parent bus
r307091:
Add compatibility string from upstream DT
r307092:
Make BCM2835 GPIO driver compatible with upstream DT
- Add compatibility string
- Make reserverd and read-only properties optional
r307093:
Make BCM283x USB driver compatible with upstream DT
- Make resource allocation logic depend on compatibility string
to check what format of DTS node should be used - FreeBSD's or upstream
r307095:
Make VCHI driver compatible with upstream DT
- Add compatibility string
- Compensate difference in base address between our custom DTB and upstream one
r307098:
Make BCM28x USB driver compatible with upstream device tree
This should have been committed in r307093: resource allocation depends
on source of the device tree. upstream dts has extra interrupt that we can
ignore
r307115:

been done by U-Boot. This allows the USB to work when we load the kernel
directly.
No dma sync is performed after these operations as the data we read/write
is not used by the cpu after the calls to the maimbox driver.

- Rework how we allocate and free USB host channels, so that we only
allocate a channel if there is a real packet going out on the USB
cable.
- Use BULK type for control data and status, due to instabilities in
the HW it appears.
- Split FIFO TX levels into one for the periodic FIFO and one for the
non-periodic FIFO.
- Use correct HFNUM mask when scheduling host transactions. The HFNUM
register does not count the full 16-bit range.
- Correct START/COMPLETION slot for TT transactions. For INTERRUPT and
ISOCHRONOUS type transactions the hardware always respects the ODDFRM
bit, which means we need to allocate multiple host channels when
processing such endpoints, to not miss any so-called complete split
opportunities.
- When doing ISOCHRONOUS OUT transfers through a TT send all data
payload in a single ALL-burst. This deacreases the likelyhood for
isochronous data underruns.
- Fixed unbalanced unlock in case of "dwc_otg_init_fifo()" failure.
- Increase interrupt priority.

to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.
Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.
