target/ppc: Move VSX arithmetic and max/min insns to decodetree.

Moving the following instructions to decodetree specification:

	x{s, v}{add, sub, mul, div}{s, d}p	: XX3-form
	xs{max, min}dp, xv{max, min}{s, d}p	: XX3-form

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