feat(cpus): workaround for Cortex-A520(2938996) and Cortex-X4(2726228)
This patch implements errata functions for two errata, both of them
disable TRBE as a workaround. This patch doesn't have functions
that disable TRBE but only implemented helper functions that are
used to detect cores affected by Errata 2938996(Cortex-A520) & 2726228(Cortex-X4)
