power_supply: Add inlmt,iterm, min/max temp props
Add new power supply properties for input current, charge termination
current, min and max temperature
POWER_SUPPLY_PROP_TEMP_MIN - minimum operatable temperature
POWER_SUPPLY_PROP_TEMP_MAX - maximum operatable temperature
POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT - input current limit programmed
by charger. Indicates the input current for a charging source.
POWER_SUPPLY_PROP_CHARGE_TERM_CURRENT - Charge termination current used
to detect the end of charge condition
