fix(cpus): workaround for Cortex-X4 erratum 3887999

Cortex-X4 erratum 3887999 is a Cat B erratum that applies
to all revisions <= r0p3 and is still open.

The erratum can be avoided by setting CPUACTLR2[22] to 1'b1 which will
disable linking multiple Non-Cacheable or Device GRE loads to the same
read request for the cache-line. This might have a significant
performance impact to Non-cacheable and Device GRE read bandwidth for
streaming scenarios

fix(cpus): workaround for Cortex-X4 erratum 3701758

Cortex-X4 erratum 3701758 that applies to r0p0, r0p1, r0p2 and r0p3
is still Open.

The workaround is for EL3 software that performs context save/restore
on a change of Security state to use a value of SCR_EL3.NS when
accessing ICH_VMCR_EL2 that reflects the Security state that owns the
data being saved or restored.

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.

Setting this chicken bit might have a small impact on power
and negligible impact on performance.
