fix(cpus): workaround for Cortex-X3 erratum 2372204
Cortex-X3 erratum 2372204 is a Cat B erratum that applies to revisions
r0p0 and r1p0. It is fixed in r1p1.
The workaround is to set bit[40] of CPUACTLR2_EL1 to disable folding
of demand requests into older prefetches with L2 miss requests
outstanding.
