target/ppc: Move VSX logical instructions to decodetree.

Moving the following instructions to decodetree specification :

	xxl{and, andc, or, orc, nor, xor, nand, eqv}	: XX3-form

The changes were verified by validating that the tcg ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
