fix(errata): workaround for Cortex-X2 erratum 2371105

Cortex-X2 erratum 2371105 is a cat B erratum that applies to
revisions r0p0 - r2p0 and is fixed in r2p1. The workaround is to
set bit[40] of CPUACTLR2_EL1 to disable folding of demand requests
into older prefetches with L2 miss requests outstanding.
