fix(errata): workaround for Neoverse-N2 erratum 2376738

Neoverse-N2 erratum 2376738 is a Cat B erratum that applies
to revision r0p0 of the CPU. It is fixed in r0p1. 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.
