dt-bindings: batterydata: Add jeita-fcc-scaling related properties

Browse source 
Add below propeties to enable and configure jeita-fcc-scaling
algorithm :

qcom,jeita-fcc-scaling
qcom,jeita-fcc-scaling-temp-threshold
qcom,jeita-scaling-min-fcc-ua

All of this property needs to be set with valid values to enable
jeita based fcc scaling.

This should be in decidegree and if not specified
default select value is 10 DeciDegC.
<RISE_HYS_DECIDEG_C, FALL_HYS_DECIDEG_C>
- qcom,jeita-fcc-scaling: A bool property to indicate if temperature based
jeita fcc scaling is enabled. If defined, enables
scaling of FCC based on battery-temperature. Scales
the FCC depending upon the granularity of increase in
battery temperature.
- qcom,jeita-fcc-scaling-temp-threshold: A tuple entry to allow configuring the
min and max battery temperature threshold (in DeciDegC)
for jeita fcc scaling algorithm to kick in.
<MIN_BATT_TEMP_DECIDEG_C, MAX_BATT_TEMP_DECIDEG_C>
- qcom,jeita-scaling-min-fcc-ua : This value corresponds to the minimum FCC (in uA) of
the battery to be applied when battery temperature hits the max
temperature indicated it "qcom,jeita-fcc-scaling-temp-threshold".
This value is selected based on profiling after making sure that
the battery-temperature does not rise at this FCC.
Profile data node required subnodes:
- qcom,fcc-temp-lut : An 1-dimensional lookup table node that encodes
temperature to fcc lookup. The units for this lookup
