fix(errata): workaround for Cortex-X2 erratum 2147715

Cortex-X2 erratum 2147715 is a Cat B erratum that applies to revision
r2p0 and is fixed in r2p1. The workaround is to set CPUACTLR_EL1[22]=1,
which will cause the CFP instruction to invalidate all branch predictor
resources regardless of context.
