dt-bindings: arm: sunxi: Add new board names for A523 generation

The new Allwinner A523 SoC family comes in different packages, though
they all share the same die, and so the devicetree bindings.

Add three board names that use a version from this SoC family:
- The Avaota A1: an Open Source hardware router board.
- The Radxa Cubie A5E: a typical development board
- The X96QPro+: a TV box

Add their compatible name to the list.
