[WIP] AXP313A(for Mango Pi MQ-Quad) support

[SASANO Takayoshi]

Hello,

Now I am trying to run U-Boot on Mango Pi MQ-Quad board.

This board requires AXP313A driver and it is implemented.
The diff is at GitHub,
https://github.com/u-boot/u-boot/compare/master...jg1uaa:u-boot:mq

Before submitting the diff, I want to know board configuration
(configs/mangopi_mq_quad_defconfig and
arch/arm/dts/sun50i-h616-mangopi-mq-quad.dts) is correct.

At least OpenBSD for Allwinner H616 (RAMDISK kernel for installer)
looks working like this:
