Currently, PMUv3 driver is only available for ARMv8 aarch64
platforms, ARMv8 running in aarch32 mode dont have access to
the driver. This is, especially, a problem for ARMv8 platforms
that only have aarch32 support, like the Cortex-A32.

FWIW, I've pushed out my own interpretation of this series to [1],
including the changes I suggested. The results seems to correctly work
in a 32bit guest on a 64bit host, which is what I (used to) care
about.

Feel free to pick it up.
