If you just pass the format to this function you can move rest of the
for loop also to this function.
As a second thought, this would defeat the purpose of the split. We
don't have to call _dpu_crtc_setup_blend_cfg() or setup mixer_op_mode
for the second pipe separately. So, I'd leave the loops as is.
Also, you will be able to add the trace_dpu_crtc_setup_mixer() with
complete information.
trace_dpu_crtc_setup_mixer is currently missing te stage_idx which is
important to debug blend issues.
