target/ppc: Remove MSR_SA and MSR_AP from hflags
Nothing within the translator -- or anywhere else for that matter -- checks MSR_SA or MSR_AP on the 602. This may be a mistake. However, for the moment, we need not record these bits in hflags. This allows us to simplify HFLAGS_VSX computation by moving it to overlap with MSR_VSX.
