DSU-110 erratum 2313941 is a Cat B erratum and applies to revisions
r0p0, r1p0, r2p0, r2p1, r3p0, r3p1 and is still open.
The workaround sets IMP_CLUSTERACTLR_EL1[16:15] bits to 0b11 to disable
clock gating of the SCLK domain. This will increase the idle power
consumption.
This patch applies the fix for Cortex-X2/A510/A710 and Neoverse N2.

This erratum workaround is a bit different because it interacts with a
feature supported in TFA. The typical method of implementing an errata
workaround will not work in this case as the MPMM feature would just be
re-enabled by context management at every core power on after being
disabled by the errata framework. So in addition to disabling MPMM, this
workaround also sets a flag in the MPMM runtime framework indicating
that the feature should not be enabled even if ENABLE_MPMM=1.

Cortex-A510 erratum 1922240 is a Cat B erratum that applies to revision
r0p0 and is fixed in r0p1.
Since no errata framework code existed for A510 prior to this patch, it
has been added as well. Also some general cleanup changes in the CPU lib
makefile.
