This part of mentioned commit, was missed by my mistake during the rebase. Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> 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.
