This patch adds ARM Performance Monitor Unit dt node for exynos7.
PMU provides various statistics on the operation of the CPU and
memory system at runtime, which are very useful when debugging or
profiling code. This enables the same.

[krzk: Squashed with "Add level for cpu dt node for exynos7"]
Signed-off-by: NKrzysztof Kozlowski <krzk@kernel.org>

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).
