[PATCH v2 6/6] arm64: dts: allwinner: h6: add Rongpin RP-H6C SoM and RP-H6B board

From: Icenowy Zheng
Date: Fri Dec 02 2022 - 03:20:47 EST

Rongpin RP-H6C is an Allwinner H6 SoM by Rongpin, with Allwinner H6 SoC,
AXP805 PMIC, LPDDR3 memory and eMMC storage on it.

RP-H6B is their official evaluation board of RP-H6C, with an onboard
GL850G USB hub, Ampak AP6212 Wi-Fi module and some circuits about LVDS
display. It also exports the OTG USB port, the USB 3.0 port, PCIe bus
(as mPCIe slot), internal Ethernet PHY, analog audio/video and HDMI
port.

Add a DTSI file for the SoM and a DTS for the full board.

Changes in v2:
- Name all regulator nodes regulator-xxx.
- Fixed underscores in node names.
