Documentation: batterydata: Add avg vbat step charging support 



Add support to specify average battery votlage based step charging
using qcom,vbat-avg-based-step-chg property. While at it, add
support to define whether to change the FCC directly or in steps
of pre-configured value using the property qcom,taper-fcc.
