[U-Boot] [PATCH 01/15][v2] power: pmic: add pfuze3000 support

[Adrian Alonso]

* Add pmic pfuze3000 support, implement power_pfuze3000_init to be
  used in power_init_board callback function.

Changes for V2:
- Correct pfuze device name to pfuze3000; Freescale documentation uses
  Pfuze 3000 as product name for the pmic, align driver name with the
  actual product name.
