Cortex-A510 erratum 2250311 is a Cat B erratum that applies to revisions
r0p0, r0p1, r0p2, r0p3 and r1p0 and is fixed in r1p1.

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.
