dt-bindings: arm: sunxi: document Remix Mini PC name

The Jide Remix Mini PC is a mini computer that ships with the Remix OS
Android based system. The SoC is an Allwinner H64, which is very close,
if not identical to the Allwinner A64.

Add the board/SoC compatible string pair to the list of known boards.
There are some drivers that look explicitly for the A64 compatible name,
so retain this name to increase compatibility.
