fix(errata): workaround for Cortex-A710 erratum 2058056

Cortex-A710 erratum 2058056 is a Cat B erratum that applies to
revisions r0p0, r1p0, and r2p0. It is still open. The workaround
is to write the value 4'b1001 to the PF_MODE bits in the
IMP_CPUECTLR2_EL1 register which will place the data prefetcher
in the most conservative mode instead of disabling it.
