pmic: Extend PMIC framework to support battery related commands

Browse source 
Two extra commands:
"pmic name bat state" and "pmic name bat charge" has been added to
pmic framework. Those provides state display and charge capabilities
to named batteries.

The pmic_core.c file has been refactored to more consistent name scheme.
