dt-bindings: qpnp-fg-gen4: Add properties to support SW based SOC scaling 



Add qcom,soc-scale-mode-en, qcom,soc-scale-vbatt-mv, qcom,soc-scale-time-ms
properties to support SW based SOC scaling using filtered battery voltage.
This helps on aged batteries, where SOC calculated by FG can remain high
for low battery voltage.

- qcom,soc-scale-mode-en

	Usage:      optional

	Value type: <boolean>

	Definition: A boolean property that when specified will enable scaling

		    of the SOC linearly, based on the filtered battery voltage

		    after crossing below a Vbatt threshold.



- qcom,soc-scale-vbatt-mv

	Usage:      optional

	Value type: <u32>

	Definition: Threshold voltage to decide when SOC should

		    be scaled based on filtered voltage when

		    qcom,soc-scale-mode-en is specified. If this

		    is not specified, then the default value is 3400.

		    Unit is in mV.



- qcom,soc-scale-time-ms

	Usage:      optional

	Value type: <u32>

	Definition: Timer value for doing SOC calculation based on

		    filtered voltage when qcom,soc-scale-mode-en is

		    specified. If this is not specified, then the

		    default value is 10000. Unit is in ms.
