riscv: dts: spacemit: k1-orangepi-rv2: add SD card support with UHS modes
Add complete SD card controller support with UHS high-speed modes.
- Enable sdhci0 controller with 4-bit bus width
- Configure card detect GPIO with GPIO_ACTIVE_LOW logic
- Connect vmmc-supply to buck4 for 3.3V card power
- Connect vqmmc-supply to aldo1 for 1.8V/3.3V I/O switching
- Add dual pinctrl states for voltage-dependent pin configuration
- Support UHS-I SDR25, SDR50, and SDR104 modes
- Add stable MMC device aliases (mmc0 = eMMC, mmc1 = SD card)
This enables full SD card functionality including high-speed UHS modes
for improved performance.
