fix(cpus): workaround for Cortex-X3 erratum 2070301
Cortex-X3 erratum 2070301 is a Cat B erratum that applies to all
revisions <= r1p2 and is still open.
The workaround is to write the value 4'b1001 to the PF_MODE bits
in the IMP_CPUECTLR2_EL1 register. This places the data prefetcher
in the most conservative mode instead of disabling it.
