Original commit message:
power: pmic: pfuze100 support driver model

1. Support driver model for pfuze100.
2. Introduce a new Kconfig entry DM_PMIC_PFUZE100 for pfuze100
3. This driver intends to support PF100, PF200 and PF3000, so add
   the device id into the udevice_id array.
4. Rename PMIC_NUM_OF_REGS macro to PFUZE100_NUM_OF_REGS.
