fix(cpus): workaround for Cortex-A78C erratum 2779484
Cortex-A78C erratum 2779484 is a Cat B erratum that applies to
revisions r0p1 and r0p2 and is still open.
The workaround is to set the CPUACTLR3_EL1[47] bit to 1. Setting this
bit might have a small impact on power and negligible impact on
performance.
