Start to remove the old pre-INTRNG code from the arm platforms. These have
all moved to use INTRNG.

INTRNG - use gpio interrupt modes definitions added in r298738 and
implement also GPIO_INTR_EDGE_BOTH mode. All reasonable interrupt
modes are supported now.

Rename ARM_INTRNG and MIPS_INTRNG to INTRNG. This will help with machine
independent code that needs to know about INTRNG such as PCI drivers.

Switch TI platform support code from using FreeBSD's custom-baked DTS
files to vendor-provided ones. It should make easier to adopt platform
code to new revisions of hardware and to use DTS overlays for various
Beaglebone extensions (shields/capes).

Original dts filenames were not changed, they're now wrappers over dts
files provided by TI. So make sure you update .dtb files on your
devices as part of kernel update

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3

On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt
on serial port in multiuser mode. Single user mode serial console
should work as-is

Add interrupt support for GPIO pins on OMAP4 and AM335x.

This enables the use of GPIO pins as interrupt sources for kernel devices
directly attached to gpiobus (userland notification will be added soon).

The use of gpio interrupts for other kernel devices will be possible when
intrng is complete.

All GPIO pins can be set to trigger on:

- active-low;
- active-high;
- rising edge;
- falling edge.

Tested on: Beaglebone-black

Bring in the last round of updates before adding the interrupt support.

Fix the following issues:

- Removed revision from device softc, it isn't used anywhere else out of
device attach routine;

- Move the duplicated code for verification of valid banks (and pins) to
a single function;

- Use some macros to simplify the handling of some constants;

- Update some stale comments.
