This series is extracted from [4], which is trying to remove all
traces of gic_arch_extn from the tree. As some maintainers are more
responsive than others (understatement of the year...), I've decided
to split it per sub-arch, and get it moving, at least partially.
This series addresses Exynos by converting its PM support to a stacked
domain on top of the standard GIC.
Based on 4.0-rc1.
* From v4: [4]
- Extracted from the full series
- Rebased on 4.0-rc1
* From v3 [3]:
- Rebased on top of the patch working around hardcoded IRQ on OMAP4/5 [4]
- Fixed more iMX6 DTs (Stephan)
- Fixed Exynos4/5 DTs
* From v2 [2]:
- Addressed numerous comments from Thierry
- Merged bug fixes from Nishanth
- Merged bug fix from Stefan
* From v1 [1]:
- Rebased on 3.19-rc3
- Fixed a number of additional platforms
- Added crossbar conversion to stacked domains
- Merged bug fixes from Nishanth

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 stronly suspect that there is more than two wake-up interrupts on these platforms, but I leave it to the maintainers to fix their mess.
