fix(errata): workaround for Cortex-A78 erratum 2376745

Cortex-A78 erratum 2376745 is a cat B erratum that applies to revisions
r0p0 - r1p2 and is still open. The workaround is to set bit[0] of
CPUACTLR2 which will force PLDW/PFRM ST to behave like PLD/PRFM LD and
not cause invalidation to other PE caches.
