This is needed with the pl011 driver. Before this change it would default
to a shift of 0, however the hardware places the registers at 4-byte
addresses meaning the value should be 2.
This patch fixes this for the pl011 when configured using the fdt. The
other drivers have a default value of 0 to keep this a no-op.

It seems that this 'simplification' was copied to all GPIO drivers in tree.
This fix a bug where a GPIO controller could fail to attach its children
(gpioc and gpiobus) if another GPIO driver attach first.
(4 in operation), 4GB ram (3.5 usable) ARM machine.
Support covers device drivers for:
- Serial Peripheral Interface (SPI)
- Chrome Embedded Controller (EC) - SPI-based version
- XHCI and USB 3.0 dual-role device PHY
Also:
- Add support for Exynos5420 in Pad module
- Move power-related functions to separate driver --
Power Management Unit (PMU)
- Enable XHCI for Chromebook1
Special thanks to grehan@ for hardware, and to

o Allow setting keymap in FDT, use hardcoded one by default
o Represent fallback keymap as a list rather than directly usable M*N array

platform code, it is expected these will be merged in the future when the
ARM code is more complete.
Until more boards can be tested only use this with the Raspberry Pi and
rrename the functions on the other SoCs.

Support covers device drivers for:
- Interrupt Combiner
- gpio/pad, External Interrupts Controller (pad)
- I2C Interface
- Chrome Embedded Controller
- Chrome Keyboard
Also:
- Use new gpio dev class in EHCI driver
- Expand device tree information
and the functionality it provided into arm/exception.S. Rename the main
irq handling routine from arm_handler_execute() to arm_irq_handler() to
make it more congruent with how other exception handlers are named, and
also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.
appropriate for each of the 'foo' in the tree. This will allow us to
compile them together (although symbol conflicts prevent us from doing
that today, this just fixes the file name collision).

mptramp() function from everywhere except AramadaXP (and I think it's
really not used there either, because the code that references it appears
to be insanely does-nothing in nature).
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.
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.
This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.
A similar change was made in OpenBSD.
