riscv: dts: spacemit: k1-musepi-pro: add SD card support with UHS modes
Update the Muse Pi Pro devicetree with SD card support to match what
was done for the OrangePi RV2 in [1]. More precisely:
- Enable sdhci0 controller with 4-bit bus width
- Configure card detect GPIO with internal pull-up support
- 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)
