regulator: fan53555: Add support for mode operations on Silergy devices

Make the PWM mode configurable from devicetree. Some boards require forced
PWM mode to keep the supply ripple within acceptable limits under light
load conditions

Support is restricted to Silergy manufacturer as it is the only one
currently tested.
