target/ppc: Move floating-point move instructions to decodetree.

Move below instructions to decodetree specification:

	f{mr, neg, abs, nabs}		: X-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.
