[v5,4/5] drm/msm/dpu: rename enable_compression() to program_intf_cmd_cfg()
Commit Message
Rename the intf's enable_compression() op to program_intf_cmd_cfg()
and allow it to accept a struct intf_cmd_mode_cfg to program
all the bits at once. This can be re-used by widebus later on as
well as it touches the same register.
changes in v5:
- rename struct intf_cmd_mode_cfg to dpu_hw_intf_cmd_mode_cfg
- remove couple of comments
