  AMDGPU: Delete seemingly dead s_fmaak_f32/s_fmamk_f32 folding code

No tests fail with this. I'm not sure I understand the comment,
there can't be any folding into an operand that had to already
be a constant. I tried different combinations of immediates to these
instructions but never hit the condition.
