power_supply: Add boot and calibration attributes
Usually PMIC's come with coulomb counting mechanism which can be used to implement a Fuel Gauginig solution in Software itself. One of key input to these SW Fuel Gauge solutioons is the boot up parameters like boot voltage and boot current. This patch adds the VOLTAGE_BOOT and CURRENT_BOOT power supply attributes to report bootup voltage and current. This patch also adds CALIBRATE power supply attribute which useful is for calibrating the battery/coulomb counter.
