Subject: [PATCH v3 9/9] ARM: dts: sun8i: s3: add devicetree for Lichee zero plus w/ S3

Lichee zero plus is a core board made by Sipeed, which includes on-board
TF slot or SMT SD NAND, and optional SPI NOR or eMMC, a UART debug
header, a microUSB slot and a gold finger connector for expansion. It
can use either Sochip S3 or Allwinner S3L SoC.

Add the basic device tree for the core board, w/o optional onboard
storage, and with S3 SoC.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>

Changes in v3:
- Drop common regulator DTSI usage and added vcc3v3 regulator.
