halapi: power: Add new PASS_RESOURCE_BATTER_ID for battery h/w

The battery h/w resource is very important in order to prevent
the dangerous situation such as fire, skin burn and so on.

So that it must need to monitor the temperature of battery
and then if over-temperature is detected, need to change
the battery status like discharging for decreasing the temperture
until safe tempeature.
