As promised, this a resend of the new drivers which missed the boat last
cycle. No material changes since the respective v3s, just rebasing, and
I decided I may as well post them together as a series to pre-resolve
the Kconfig/Makefile conflicts. I've also revived the BMU DT patches
from v2, as some interest has been expressed from within Arm, but again
they can still be considered somewhat optional as it's only the first
two which the AGI CPU folks are clamouring for right now.

Cheers,
Robin.
