target-arm: Implement ARMv8 MVFR registers
For ARMv8 there are two changes to the MVFR media feature registers:
* there is a new MVFR2 which is accessible from 32 bit code
* 64 bit code accesses these via the usual sysreg instructions
rather than with a floating-point specific instruction
Implement this.
