sunxi: Add support for Anbernic RG35XX-2024

The Anbernic RG35XX series of devices are based around an Allwinner
H700 SoC with 1GB of RAM, 2 SD cards, and multiple input buttons.

This bootloader has been tested on the Anbernic RG35XX-2024 and
RG35XX-H, but should be suitable for the entire lineup of H700 based
devices.

A future series of updates will add board selection logic to identify
and load the correct device tree automatically.
