[PATCH v5 0/7] irqchip: Move OMAP{4,5}/DRA7 to use stacked domains

[Marc Zyngier]

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 OMAP{4,5} by converting the WUGEN to stacked
domains. The DRA7 crossbar gets the same treatment.

It is worth realizing that:

- I haven't been able to test this as much as I would have wanted to
  (it's only been tested on omap4 and omap5).

- This actively *breaks* existing setups. Once you boot a new kernel
  with an old DT, suspend/resume *will* be broken. Old kernels on a
  new DT won't even boot! You've been warned. This really outline the
  necessity of actually describing the HW in device trees...

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
