This adds support for the Radxa Zero SBC. The device-tree is loosely
based upon existing support for SEI510 and U200 (also G12A boards)
and has been developed with the 4/32 board configuration.

Changes since v1:
- Drop flash_1v8 and use vcc_1v8
- Rename dc_in to ao_5v
- Rename vcc_5v to hdmi_pw and drop GPIO control

Radxa Zero is a small form factor SBC based on the Amlogic S905Y2
chipset that ships in a number of RAM/eMMC configurations:

Boards with 512MB/1GB LPDDR4 RAM have no eMMC storage and BCM43436
wireless (2.4GHz b/g/n) while 2GB/4GB boards have 8/16/32/64/128GB
eMMC storage and BCM4345 wireless (2.4/5GHz a/b/g/n/ac).

- Amlogic S905Y2 quad-core Cortex-A53
- Mali G31-MP2 GPU
- HDMI 2.1 output (micro)
- 1x USB 2.0 port - Type C (OTG)
- 1x USB 3.0 port - Type C (Host)
- 1x micro SD Card slot
- 40 Pin GPIO header
