drm: mxsfb: Use bus_format from the nearest bridge if present

Browse source

In case there is a bridge connected to the LCDIF, use bus_format
from the bridge, otherwise behave as before and use bus_format
from the connector. This way, even if there are multiple bridges
in the display pipeline, the LCDIF will use the correct format.
