But that would require some more work for dynamic assignment of TCONs to CRTCs, which is way out of scope for this series. So, Reviewed-by: Chen-Yu Tsai <wens@csie.org> I'll think about if and how this could be done.

R40 has 4 TCONs, but only 2 of them can receive some kind of output at the same time. Let's disable them by default, so only those which are really connected on board can be enabled in board dts file.
