The "correct" approach is clearly to just have the drm core change the
i2c mux before requesting edid, but that's made difficult because of the
absence of ordering guarantees in initialisation. I don't like quirking
this, since we're then back to the situation of potentially having to
add every new piece of related hardware to the quirk list.
