power: core: add power supply APIs

Browse Source 
Rename power_supply_set_charging_by to power_supply_set_online to
more accurately reflect the intent of the API.

Add power_supply_set_charge_type to enable a charger driver to set
a POWER_SUPPLY_PROP_CHARGE_TYPE. Ultimately this is handled like
a request, the receiving charger driver then can handle the request
and report the adequate POWER_SUPPLY_PROP_CHARGE_TYPE once necessary
action has been taken.
