fix(cpus): workaround for Cortex-A78C erratum 2376749
Cortex-A78C erratum 2376749 is a Cat B erratum that applies
to revisions r0p1 and r0p2 of the A78C and is currently open.
The workaround is to set CPUACTLR2_EL1[0] to 1 to force
PLDW/PFRM ST to behave like PLD/PRFM LD and not cause
invalidations to other PE caches.
