ARM: Tidy up representation of PKH instruction.

The shift type is implied by the instruction (PKHBT vs. PKHTB) and so shouldn't
be also encoded as part of the shift value immediate. Otherwise we're able to
represent invalid instructions, plus it needlessly complicates the
representation. Preparatory work for asm parsing of these instructions.
