Currently, PMUv3 driver is only available for ARMv8 aarch64 platforms,

This is, especially, a problem for ARMv8 platforms that only have
aarch32 support, like the Cortex-A32.

Make the PMUv3 driver available to arm arch (ARMv8 aarch32) by moving
the PMUv3 driver from arm64 to drivers, that makes the driver common
to both arm and arm64 architectures, then add PMUv3 arm Support.

The main work in this patchset was made a while back by Marc Zyngier
in [1]. Patchset version 1 [v1] rebases Marc's patches to the latest
kernel revision and adds additional patches to accommodate the changes
in the kernel since Marc wrote the patches.

version 2 [v2] of the patchset was created by Marc Zyngier and I
picked it up from [2].

Would appreciate being CC'd on next iterations, thanks:
