This patchseries adds support for independent DSI config to DPU1 display
subdriver. Also drop one of msm_kms_funcs callbacks, made unnecessary
now.
Tested on RB5 (dpu, dsi). Previous iteration was tested by Alexey
Minnekhanov.
Changes since v2:
- Removed Reviewed-By tags from changed patches (1, 2)
- Changed more dual DSI mentions in the patch 1
- Added msm_dsi_is_master_dsi() helper
- Rewrote dsi encoder setup function again basing on review by Abhinav
Cahanges since v1:
- Rewrote dsi encoder setup function by separating common code sequence
and calling it either for the bonded interface or twice for each of
the DSI hosts.
Changes since RFC:
- renamed dual DSI to bonded DSI as suggsted by Abhinav
- added comments to _dpu_kms_initialize_dsi() regarding encoders usage

To remove possible confusion (as both configurations can be referenced as dual DSI) let's rename old "dual DSI" (two DSI hosts driving single device, with clocks being locked) to "bonded DSI".
