[Devel] [PATCH] powerpc: Remove remaining debugreg bits from forward port of v22-dev patches

[Matt Helsley]

The commit 'powerpc: provide APIs for validating and updating DABR'
from ckpt-v22-dev can be dropped for v23-rc1 but other patches in
the v22-dev series for powerpc use the debugreg functions introduced
there. They can be rebased and merged with this patch and the
debugreg code can be pushed as a later, independent patch.
