arm64: errata: Add detection for TRBE trace data corruption
 
TRBE implementations affected by Arm erratum #1902691 might corrupt trace
data or deadlock, when it's being written into the memory. So effectively
TRBE is broken and hence cannot be used to capture trace data. This adds
a new errata ARM64_ERRATUM_1902691 in arm64 errata framework.
