Series [1/2] drm/msm/dpu: drop unused dpu_kms from interface initialization |

Commit Message

  dpu_kms seems unused while initializing DSI, HDMI and DP through
their respective _dpu_kms_initialize_* functions.

Hence lets drop the parameter altogether.

This breaks now on top of YUV patchset:

drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c: In function
'_dpu_kms_initialize_displayport':
drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c:583:35: error: 'dpu_kms'
undeclared (first use in this function)
583 | yuv_supported = !!dpu_kms->catalog->cdm;

As this requires adding of the yuv_supported argument, let's consider
moving it backwards: for  _dpu_kms_initialize_writeback() we can get
format_list and n_formats from the dpu_kms.
