Check presence of fix for errata 843419 in Cortex-A53
A fix for errata 843419 may be available in revision r0p4 of the
Cortex-A53 processor. The presence of the fix is determined by checking
bit 8 in the REVIDR register.
If the fix is present we report ERRATA_NOT_APPLIES which silences the
erroneous 'missing workaround' warning.
