freedreno/ir3: switch PIPE_CAP_TGSI_TEXCOORD

Browse source 
We don't really need the varying remapping, and it seems to somehow
happen twice when shader-cache comes into the picture.  But we can
just choose not to have this problem.

Now that everything is using the ir3_point_sprite() helper, we can
flip this pipe cap without it being a massive flag-day.
