fix(errata): workaround for Cortex-A78C erratum 2395411
Cortex-A78C erratum 2395411 is a Cat B erratum that affects revisions r0p1 and r0p2, and is currently open. The workaround is to set CPUACTLR2_EL1[40] to 1, which will disable folding of demand requests into older prefetches with L2 miss requests outstanding.
