arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs

Add KRYO4XX gold/big cores to the list of CPUs that need the
repeat TLBI workaround. Apply this to the affected
KRYO4XX cores (rcpe to rfpe).

The variant and revision bits are implementation defined and are
different from the their Cortex CPU counterparts on which they are
based on, i.e., (r0p0 to r3p0) is equivalent to (rcpe to rfpe).
