Cortex-X4 erratum 2763018 is a Cat B erratum that is present
in revisions r0p0, r0p1 and is fixed in r0p2.

The workaround is to set bit[47] of CPUACTLR3_EL1 register.
Setting this chicken bit might have a small impact on power
and negligible impact on performance.

fix(cpus): workaround for Cortex-X4 erratum 2701112

Cortex-X4 erratum 2701112 is cat B erratum that applies to
revision r0p0 and is fixed in r0p1. This erratum affects
system configurations that do not use an Arm interconnect IP.

The workaround for this erratum is not implemented in EL3.
The erratum can be enabled/disabled on a platform level.
The flag is used when the errata ABI feature is enabled and can
assist the Kernel in the process of mitigation of the erratum.
