Cortex-A53: Fix reporting of missing errata when not needed
Cortex-A53: Fix reporting of missing errata when not needed

Errata 819472, 824069, and 827319 are currently reported in a warning as
missing during boot for platforms that do not need them. Only warn when
the errata is needed for a given revision but not compiled in like other
errata workarounds.

Fixes: bd393704d2b1 ("Cortex-A53: Workarounds for 819472, 824069 and 827319")
