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.
