OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.
This patch does just this, updating the DT files to actually
reflect what the HW provides.
BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.
On a platform with this patch applied, the system looks like
this:

The DSS data lines don't need pulls, it's best
to remove them to guarantee signal integrity.

AM437x Starter Kit already has discrete pullups
for all I2C buses, so we can (and should) remove
internal pulls.

This patch just makes USB[01]_DRVVBUS signal
explicitly muxed. Note that board already has
a discrete pulldown, so we're not adding any
pulls here.

By don't relying on implicit MMC0 pulldown we
make sure that pins are marked busy and even
if we have a broken bootloader, MMC0 will
remain functional.

The lcd0 node for am437x-sk-evm.dts contains bad LCD timings, and while
they seem to work with a quick test, doing for example blank/unblank
will give you a black display.
This patch updates the timings to the 'typical' values from the LCD spec
sheet.
Also, the compatible string is completely bogus, as
"osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on
the board is a newhaven one. Update the compatible string to reflect
this. Note that this hasn't caused any issues, as the "panel-dpi"
matches the driver.

Caused by a copy & paste error. Note that even with
this bug AM437x SK display still works because GPIO
mux mode is always enabled. It's still wrong to mux
somebody else's pin.
Luckily ball D25 (offset 0x238 - gpio5_8) on AM437x
isn't used for anything.
While at that, also replace a pullup with a pulldown
as that gpio should be normally low, not high.

DCDC3 supplies voltage to DDR. Fix DCDC3 volatge to 1.5V which is the reset
value. Programming to a non-reset value while executing from DDR will result
in random hangs.
