The A10s has an HDMI controller connected to the second TCON channel. Add
it to our DT.

Since the TV Encoder was the only channel 1 user so far, also add the
property now that we have several users.

I assume this indicates a difference between A10s and A13, namely the former
has an HDMI controller. The compatible string should be documented.

Missing reg property here, since you have #address-cells = 1.

Otherwise,
