Neoverse-N2 erratum 2388450 is a cat B erratum that applies to
revision r0p0 and is fixed in r0p1. The workaround is to set
bit[40] of CPUACTLR2_EL1 to disable folding of demand requests into
older prefetches with L2 miss requests outstanding.

executing a store exclusive to the same cache line address to fail
continuously."

The erratum is avoided by setting CPUACTLR2_EL1[0] to 1 to force

to other PE caches. There might be a small performance degradation
to this workaround for certain workloads that share data.

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.
