target/arm: Enforce M-profile VMRS/VMSR register restrictions
For M-profile before v8.1M, the only valid register for VMSR/VMRS is
the FPSCR. We have a comment that states this, but the actual logic
to forbid accesses for any other register value is missing, so we
would end up with A-profile style behaviour. Add the missing check.
