fix(errata): workaround for  Cortex-A710 2282622

Cortex-A710 erratum 2282622 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r2p0, and is fixed in r2p1. The workaround is to set
CPUACTLR2_EL1[0] to 1, which will force PLDW/PFRM ST to behave like
PLD/PRFM LD and not cause invalidations to other PE caches.
