riscv: dts: starfive: add Milk-V Mars CM Lite system-on-module
Milk-V Mars CM Lite is a System-on-Module based on the Milk-V Mars CM
without the onboard eMMC storage component populated and configured
instead for SD3.0 Card Slot on that interface via 100-pin connector.
Link to Milk-V Mars CM Lite schematics: https://github.com/milkv-mars/mars-files/tree/main/Mars-CM_Hardware_Schematices
Link to StarFive JH7110 Technical Reference Manual: https://doc-en.rvspace.org/JH7110/TRM/index.html
Link to Raspberry Pi CM4IO datasheet: https://datasheets.raspberrypi.com/cm4io/cm4io-datasheet.pdf
Add the devicetree file to make use of StarFive JH7110 common supported
features PMIC, EEPROM, UART, I2C, GPIO, PCIe, QSPI Flash, PWM, and
Ethernet. Also configure the eMMC interface mmc0 for SD Card use and
configure the common SD Card interface mmc1 for onboard SDIO BT+WiFi.
