-Required properties:
-- compatible: Should be one of the following:
-  "sprd,sc2720-fgu",
-  "sprd,sc2721-fgu",
-  "sprd,sc2723-fgu",
-  "sprd,sc2730-fgu",
-  "sprd,sc2731-fgu".
-- reg: The address offset of fuel gauge unit.
-- battery-detect-gpios: GPIO for battery detection.
-- io-channels: Specify the IIO ADC channels to get temperature and charge voltage.
-- io-channel-names: Should be "bat-temp" or "charge-vol".
-- nvmem-cells: A phandle to the calibration cells provided by eFuse device.
-- nvmem-cell-names: Should be "fgu_calib".
-- sprd,calib-resistance-micro-ohms: Specify the real resistance of coulomb counter
-  chip in micro Ohms.
-- monitored-battery: Phandle of battery characteristics devicetree node.
