mmc: sdhci-of-k1: add regulator and pinctrl voltage switching support
Add voltage switching infrastructure for UHS-I modes by integrating both
regulator framework (for supply voltage control) and pinctrl state
switching (for pin drive strength optimization).
- Add regulator supply parsing and voltage switching callback
- Add optional pinctrl state switching between "default" (3.3V) and
"state_uhs" (1.8V) configurations
- Enable coordinated voltage and pin configuration changes for UHS modes
This provides complete voltage switching support while maintaining
backward compatibility when pinctrl states are not defined.
