Merge "power: smb1351-charger: Add support to work with FG"

- qcom,using-pmic-therm		This property indicates thermal pin connected to pmic or smb.

- qcom,bms-psy-name		This is a string and it points to the bms

				power supply name.

- qcom,use-external-fg		This is a bool property to indicate if the SMB charger

				working with an external Fuel Gauge(FG). If yes, the SMB

				charger would interact with FG and several software

				workarounds will be applied to improve the SoC reporting

				accuracy.

- qcom,resume-soc		This property specify an integer value to indicate

				SOC value to resume charging. This property could be

				defined when qcom,use-external-fg is defined. When this

				property is defined, recharging behavior will be based

				upon the SOC reported by FG and the recharging based on

				internal voltage will be disabled.

- qcom,iterm-ma			Specifies the termination current to indicate end-of-charge.

				Possible values in mA - 70, 100, 200, 300, 400, 500, 600, 700.

- qcom,iterm-disabled		Disables the termination current feature. This is a bool
