MIPI DSI:
- Add "vsys_lcm_reg" regulator support and setup the "mt6357_vsim1_reg",
to power the pannel plugged to the DSI connector.
- Setup the Display Parallel Interface.
- Add the startek kd070fhfid015 pannel support.
HDMI:
- Add HDMI connector support.
- Add the "ite,it66121" HDMI bridge support, driven by I2C1.
- Setup the Display Parallel Interface.
