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.

to revisions r0p0, r0p1, r0p2, r0p3, r1p0, and r1p1. It is
fixed in r1p2. The workaround is to set the ATOM field of
CPUECTLR_EL1 (bits [40:38]) to 0b010, which will force all
cacheable atomic operations to be executed near.
