Subject: [PATCH 1/4] 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_INLMT - input current limit programmed by charger. Indicates
the input current for a charging source.

POWER_SUPPLY_PROP_CHARGE_TERM_CUR - Charge termination current used to detect
the end of charge condition
