msm: kgsl: Update A3XX REG_TO_MEM opcodes in legacy context switch

Version 29 of the PM4 firmware for A3XX modified the format of the
REG_TO_MEM opcode by changing the bit shift of one the fields.
Modify the legacy context switch code accordingly.  This will break
users of older firmware, but the old firmware shouldn't ever be in
wide use anyway, so backwards compatibility is not a concern.
