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

Nit: is the 0 suffix needed? I don't see any indication that there is
a second controller.

This looks like a separate patch, probably following the binding change?

I don't know, the binding says that without anything specified, reg
would be used. I was assuming that we only needed it once we had the
new endpoint to make it consistent, therefore it didn't need an extra
patch.

But I can definitely create one if you want.

It just seems a bit out of place, that's all. Mentioning it in the
