power: batterydata: Add the ibat vs temp vs ACC lookup table

The ACC (apparent charge capacity) of the battery is a function
of the Ibat (battery current) and temperature. The ACC is used
to determine the UUC (unusable capacity of the battery).

Add the logic to parse the ibat_vs_temp_vs_acc lookup table
when specified in the battery profile.
