DPU 5.x+ and DSI 6G 2.5.x+ support a databus-widen mode that allows for more compressed data to be transferred per pclk. This series adds support for enabling this feature for both DPU and DSI by doing the following: 1. Add a DPU_INTF_DATABUS_WIDEN feature flag 2. Add a DPU INTF op to set the DATABUS_WIDEN register 3. Set the DATABUS_WIDEN register and do the proper hdisplay calculations in DSI when applicable Note: This series will only enable the databus-widen mode for command mode as we are currently unable to validate it on video mode.
