UPSTREAM: dt-bindings: power: Introduce one property to describe the battery resistance with temperature changes

Since the battery internal resistance can be changed as the temperature
changes, thus add one table to describe the battery resistance percent
in different temperatures to get a accurate battery internal resistance.
