errata: workaround for Cortex-A78 erratum 2132060

Cortex-A78 erratum 2132060 is a Cat B erratum that applies to
revisions r0p0, r1p0, r1p1, and r1p2 of CPU. It is still open.
The workaround is to write the value 2'b11 to the PF_MODE bits
in the CPUECTLR_EL1 register which will place the data prefetcher
in the most conservative mode instead of disabling it.
