We only use the mrs_Op* and mrs_CR* functions and MRS_* macros when handling userspace executing a msr/msr instruction. Move the macros to where they are used and expand the functions to just use the macros directly. While here update MRS_Op0_MASK to include bit 20 as this will cause the correct op0 value to be calculated for all instructions we decode.
