Bipin Ravi c1aa3fa555 fix(cpus): workaround for Cortex X3 erratum 2641945
Cortex X3 erratum 2641945 is a Cat B erratum that applies to all
revisions <= r1p0 and is fixed in r1p1.

The workaround is to disable the affected L1 data cache prefetcher
by setting CPUACTLR6_EL1[41] to 1. Doing so will incur a performance
penalty of ~1%. Contact Arm for an alternate workaround that impacts
power.
