powerpc/ppc-opcode: Add encoding macros for VSX vector paired instructions
Add instruction encodings, DQ, D0, D1 immediate, XTP, XSP operands as
macros for new VSX vector paired instructions,
* Load VSX Vector Paired (lxvp)
* Load VSX Vector Paired Indexed (lxvpx)
* Prefixed Load VSX Vector Paired (plxvp)
* Store VSX Vector Paired (stxvp)
* Store VSX Vector Paired Indexed (stxvpx)
* Prefixed Store VSX Vector Paired (pstxvp)
