dt-bindings: mmc: spacemit,sdhci: add pinctrl support for voltage switching
Document pinctrl properties to support voltage-dependent pin
configuration switching for UHS-I SD card modes.
Add optional pinctrl-names property with two states:
- "default": For 3.3V operation with standard drive strength
- "state_uhs": For 1.8V operation with optimized drive strength
These pinctrl states allow the SDHCI driver to coordinate voltage
switching with pin configuration changes, ensuring proper signal
integrity during UHS-I mode transitions.
