ARM: exynos4/5: convert pmu wakeup to stacked domains
Exynos 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 fact that the PMU block is actually the first interrupt controller in the chain for RTC, kernels with this patch applied wont have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs may not even boot. Also, I strongly suspect that there is more than two wake-up interrupts on these platforms, but I leave it to the maintainers to fix their mess.
