dm: power: Convert as3722 to driver model
Convert this PMIC driver to driver model and fix up other users. The regulator and GPIO functions are now handled by separate drivers. Update nyan-big to work correct. Three boards will need to be updated by the maintainers: apalis-tk1, cei-tk1-som. Also the TODO in the code re as3722_sd_set_voltage() needs to be completed.
