Thanks, good spot, yes these can be trimmed.

- AEK_FP is enabled for ARMV8A
- AEK_LSE is enabled for ARMV8_1A
- AEK_CRC is enabled for ARMV8_1A
- AEK_RDM is enabled for ARMV8_1A
- AEK_RAS is enabled for ARMV8_2A
- AEK_RCPC is enabled for ARMV8_3A
- AEK_PAUTH is enabled for ARMV8_3A
- AEK_DOTPROD is enabled for ARMV8_4A
- AEK_FLAGM doesn't default
- AEK_PERFMON doesn't default
- AEK_PREDRES doesn't default

ARMV8R inherits from ARMV8_5A.DefaultExts, so we only need the latter 3 flags.

Code now updated.
