arch-power: Fix move condition field instructions
This introduces the S field for X form instructions which
is used to specify signed versus unsigned comparison. The
Power ISA does not specify a formal name for the third
1-bit opcode field required for decoding XFX form move to
and from CR field instructions, the S field can be used
to achieve the same as it has the same span and position.
This fixes the following instructions.
* Move To Condition Register Fields (mtcrf)
* Move From Condition Register (mfcr)
