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.

No changes in v4.

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

Why do we need to mention both the S3 and S3l in the name? What are
the differences between the two, and why do you need to share a DTSI?

How can it do OTG if there's no controlable VBUS?
