riscv: dts: spacemit: k1: add SD card controller and pinctrl support

Browse source

Add SD card controller infrastructure for SpacemiT K1 SoC with complete
pinctrl support for both standard and UHS modes.

- Add sdhci0 controller definition with clocks, resets and interrupts
- Add mmc1_cfg pinctrl for 3.3V standard SD operation
- Add mmc1_uhs_cfg pinctrl for 1.8V UHS high-speed operation
- Configure appropriate drive strength and power-source properties

This provides complete SD card infrastructure that K1-based boards can
enable.
