regulator: pfuze100-regulator: add coin support
Add support for PF0200 coin cell/super capacitor charger which works as a current limited voltage source via the LICELL pin. When VIN goes below a certain threshold LICELL is used to provide power for VSNVS which is usually used to hold up secure non-volatile storage and the real-time clock on the SoC.
