The MIPI DSI PHY HDMI controller on Allwinner A64 is similar
on the one on A31.

Add A64 compatible and append A31 compatible as fallback.

No. you need both. The A64 MIPI DPHY one needs to be always set with
the A31 fallback, but the A31 is also usable on its own.

Why wouldn't be, because we don't have any difference dphy right?

That's not my point. You removed from the binding documentation that
allwinner,sun6i-a31-mipi-dphy was a valid option on its own. It's not
ok to do so.
