Ryan Everett db7eb68817 fix(cpus): workaround for Cortex-X4 erratum 3076789 ...

Cortex-X4 erratum 3076789 is a Cat B erratum that is present
in revisions r0p0, r0p1 and is fixed in r0p2.

The workaround is to set chicken bits CPUACTLR3_EL1[14:13]=0b11
and CPUACTLR_EL1[52] = 1.
Expected performance degradation is < 0.5%, but isolated
benchmark components might see higher impact.
