regulator: fan53555: add support to disable suspend voltage configuration
Currently, fan53555 regulator driver always registers for
set_suspend_voltage. This force configures the regulator to
set suspend voltage switching to a different voltage selector.
However, this might not be preferred for certain applications.
Add a device tree parameter "fcs,disable-suspend" for the
regulator which when specified will disable suspend voltage
configuration.
