Make vsx_splat_<mode>_reg use correct insn attributes.
In looking at PR target/99293, I noticed that the code in
vsx_splat_<mode>_reg used "vecmove" as the "type" insn attribute when the
"mtvsrdd" is generated. It should use "mfvsr". I also added a "p9v" isa
attribute for that alternative.

* config/rs6000/rs6000.md (vsx_splat_<mode>_reg): Use the correct
insn type attribute. Add "p9v" isa attribute for generating the
mtvsrdd instruction.
