Hello Peng, I have few comments.

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.

Please keep the new convention of file naming and use just pfuze100.c. Then, later we will remove the old files.
