drm/mediatek: Allow commands to be sent during video mode
Mipi dsi panel drivers can use mipi_dsi_dcs_{set,get}_display_brightness()
to request backlight changes.
This can be done during panel initialization (dsi is in command mode)
or afterwards (dsi is in Video Mode).
When the DSI is in Video Mode, all commands are rejected.
Detect current DSI mode in mtk_dsi_host_transfer() and switch modes
temporarily to allow commands to be sent.
