abx500-chargalg: Add abx500 charging algorithm

This is a charging algorithm driver for abx500 variants. It is the central
entity for battery driver and is responsible for charging and monitoring
the battery driver. It is a hardware independant driver and also monitors
other abx500 power supply devices.
