drm: add bus_formats and num_bus_formats fields to drm_display_info
Add bus_formats and num_bus_formats fields and drm_display_info_set_bus_formats helper function to specify the bus formats supported by a given display. This information can be used by display controller drivers to configure the output interface appropriately (i.e. RGB565, RGB666 or RGB888 on raw RGB or LVDS busses).
