Varun Wadekar 47d6f5ff16 feat(cpus): workaround for Cortex A78 AE erratum 1941500
Cortex A78 AE erratum 1941500 is a Cat B erratum that applies
to revisions <= r0p1. It is still open.

This erratum is avoided by by setting CPUECTLR_EL1[8] to 1.
There is a small performance cost (<0.5%) for setting this
bit.
