fix(cpus): workaround for Neoverse V2 erratum 2618597
Neoverse V2 erratum 2618597 is a Cat B erratum that applies to
all revisions <= r0p1 and is fixed in r0p2. The workaround is to
disable the use of the Full Retention power mode in the core (setting
WFI_RET_CTRL and WFE_RET_CTRL in IMP_CPUPWRCTLR_EL1 to 0b000).
