freedreno/ir3/a6xx: fix atomic shader outputs

Browse source 
We also need to put in the output mov.  Possibly we could just fixup the
output register to read it directly from the dummy, but that is more
work and I guess dEQP is probably the only time you encounter this.

Fixes dEQP-GLES31.functional.shaders.opaque_type_indexing.atomic_counter.const_literal_fragment
