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:

Instead use "l3_div_ck", which is the proper clock for this. "l3_div_ck"

completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.

We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee17 (pinctrl: single: Add support for wake-up interrupts)
that recently got merged. In addition to that we also needed commit
79d97015 (of/irq: create interrupts-extended property) and
9ec36caf (of/irq: do irq resolution in platform_get_irq) that
are now also merged.

So let's fix the wake-up events for some selected omaps so devices
booted in device tree mode won't just hang if deeper power states
are enabled, and so systems can wake up from suspend to the serial
port event.

Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.
