Bipin Ravi 3f9df2c6ad fix(cpus): workaround for Cortex-X3 erratum 2302506
Cortex-X3 erratum 2302506 is a cat B erratum that applies to
revisions r0p0-r1p1 and is fixed in r1p2. 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.

There might be a small performance degradation to this workaround
for certain workloads that share data.
