pinctrl: baytrail: Add pin control operations
Add implementation for:
- pin control, group information retrieval: count, name and pins
- pin muxing:
- function information (count, name and groups)
- mux setting
- gpio control (enable, disable, set direction)
- pin configuration:
- pull disable
- pull up/down and pull strength
- debounce
- any other option is treated as not supported.
