rs6000: Simplify VS[ra]* for VSX_[BDF]

When used in VSX_B, VSX_D, or VSX_F, both <VSr> and <VSa> are always
just "wa" now.  Similarly <VSr2> and <VSr3>.  The former of those is
always "wa", so we can remove the mode attribute completely.

* config/rs6000/vsx.md (define_mode_attr VSr2): Delete.
(rest of file): Replace all <VSa>, <VSr>, <VSr2>, and <VSr3> that are
used with VSX_B, VSX_D, or VSX_F, with just "wa".
