arm64: errata: pass REVIDR when matching target implementation CPUs

Browse source

When target implementation CPUs are provided, is_affected_midr_range()
accidentally passed the MIDR as both arguments to __is_affected_midr_range(),
so the REVIDR mask check operated on the wrong register.

Pass REVIDR as intended.
