fix(errata): workaround for Neoverse-V1 erratum 2294912

Neoverse-V1 erratum 2294912 is a cat B erratum that applies to revisions
r0p0 - r1p1 and is still open. The workaround is to set bit[0] of
CPUACTLR2_EL1 to force PLDW/PFRM ST to behave like PLD/PRFM LD and not
cause invalidations to other PE caches.
