powerpc64le: use common fmaf128 implementation

This defines the macro such that it should behave best on all
supported powerpc targets.  Likewise, this allows us to remove the
ppc64le specific s_fmaf128.c.

I have verified powerpc64le multiarch and powerpc64le power9
no-multiarch builds continue to generate optimize fmaf128.
