* dt/irq-fix:
  arm64: dts: Fix broken architected timer interrupt trigger

This resolves a non-obvious conflict between a bugfix from
v4.8 and a cleanup for the exynos7 platform.

f2a89d3b2b arm64: dts: Fix broken architected timer interrupt trigger
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

886e7ddda0 ARM64: zynqmp: Add missing interrupt-parent to PMU node
ZynqMP is not using global interrupt-parent setting that's why
it has to be listed in every node separately. PMU node missed it and
this patch is adding it.

e753dc0359 ARM64: zynqmp: Align gic ranges for 64k in device tree
The GIC ranges in the zynqmp device tree are only 4kb aligned. Since
commit 12e14066f we automatically deal with aliases GIC regions though,
so we can map them transparently into guests even on 64kb page size
systems.

This patch makes use of that features and sets GICC and GICV to 64kb
aligned and sized regions.
