Subject: [PATCH v4 0/4] Add board support for Sipeed LicheeRV Nano

The LicheeRV Nano is a RISC-V SBC based on the Sophgo SG2002 chip. Adds
minimal device tree files for this board to make it boot to a basic
shell.

Changes in v4:
- Add correct bindings configuration for SG2002 sdhci
- Drop commit "dt-bindings: timer: Add SOPHGO SG2002 clint" because it
  has already been merged in Daniel Lezcano git tree.
- Link to v3: https://lore.kernel.org/r/20240709-sg2002-v3-0-af779c3d139d@bootlin.com

Changes in v3:
- Remove /dts-v1/ directive from sg2002.dtsi file
- Add disable-wp property to sdhci node to avoid having a write
  protected SD card
- Drop changes in cv18xx.dtsi and cv1800b.dtsi
- Add fallback compatible to cv1800b in SDHCI node of sg2002.dtsi
- Link to v2: https://lore.kernel.org/r/20240612-sg2002-v2-0-19a585af6846@bootlin.com

Changes in v2:
- Add SDHCI support
- Change device tree name to match the Makefile
- Add oscillator frequency
- Add aliases to other UARTs
- Add aliases to GPIOs
- Move compatible for SDHCI from common DT to specific DT 
- Link to v1: https://lore.kernel.org/r/20240527-sg2002-v1-0-1b6cb38ce8f4@bootlin.com
