arch-arm: Annotate original address in CMOs
This is needed when a CMO triggers an exception (e.g. DataAbort) In that
case the faulting address should be the one encoded in the instruction
rather than the cacheline address:
According to armarm:
If a memory fault that sets FAR_EL1 is generated from a data cache
maintenance or other DC instruction, FAR_EL1[63:0] holds the address
specified in the register argument of the instruction.
