Refactor VND7050AJ sensor configuration to eliminate redundancy

Browse Source 
- Create centralized sensor multiplexer node (vnd7050aj_mux) with shared configuration
- Consolidate ADC channel, GPIO pins, and reference voltage in single location
- Update sensor bindings to reference centralized mux via sensor-mux property
- Add channel-based sensor selection using mux-channel property (0-3)
- Refactor ADC sensor library to use centralized GPIO and channel control
- Update valve library to use new vnd7050aj_mux node reference
- Eliminate duplicate ADC/GPIO definitions between voltage and current sensors
- Ensure configuration consistency and prevent mismatched settings

Benefits:
- Single source of truth for VND7050AJ hardware configuration
- Impossible to have inconsistent GPIO/ADC settings between sensors
- Simplified maintenance and scalability for additional sensors
- Clean channel-based multiplexer selection interface
