rs6000: Fix unpack for no-direct-move (PR103623)

The _dm alternative works fine for soft-float, but the _nodm variant
pattern is missing that alternative.  So, let's add that.

There probably should be an r,r,i alternative as well (or we can make it
rm,r,i), but that is for later.

	* config/rs6000/rs6000.md (unpack<mode>_nodm): Add m,r,i alternative.
