What is needed is which TCON and encoder are supposed to be muxed together. This is going to be per SoC type anyway. I have something in the works, though it's not finished yet. I think this works for now.

The muxing can actually happen on both channels on some SoCs, so it makes more sense to just move it out of the sun4i_tcon1_mode_set function and create a separate function that needs to be called by the encoders. Let's do that and convert the existing drivers.
