[RFC,0/4] Separate wb_idx and intf_idx in dpu_encoder

Message

As promised here [1], this is a follow up change to separate out
wb_idx and intf_idx for better clarity in dpu_encoder.

This also helps to easily handle boards which do not have a physical
display but can still be validated using writeback interface.

In addition, this also takes care of adding wb_idx to existing DRM prints
and traces.

Currently posting this as a RFC to get feedback on this approach and if
the reviews are positive, I can easily absorb this in the DPU writeback
series [2]

Abhinav Kumar (4):
  drm/msm/dpu: introduce a wb_idx to be used for writeback interfaces
  drm/msm/dpu: start using wb_idx in dpu_encoder_phys_wb
  drm/msm/dpu: add wb_idx to existing DRM prints in dpu_encoder
  drm/msm/dpu: add wb_idx to DRM traces in dpu_encoder
