Abhinav Kumar e67dcecda0 drm/msm/dpu: limit writeback modes according to max_linewidth 
Writeback modes were being added according to mode_config.max_width
but this is assigned to double of max_mixer_width.

For compositors/clients using a single SSPP, this will fail
the dpu_plane's atomic check as it checks for max_linewidth.

Limit writeback modes according to max_linewidth to allow
even compositors/clients which use only a single SSPP to
use writeback.

Fixes: 77b001acdc ("drm/msm/dpu: add the writeback connector layer")
