Add basic device-tree for the Genio 700 EVK board. The
Genio 700 EVK is based on MediaTek MT8390 SoC.
MT8390 hardware register maps are identical to MT8188.

The Genio 700 EVK has following features:

Use proper defines.

Fixed remaining 3 defines of gpio value, will send v2.

Why do you need two default entries? This should be just one, shouldn't it?


Fixed.
