power: pm8921-bms: Update the FCC learning algorithm
1. Add configurable parameters to
- enable/disable fcc learning
- minimum soc to start FCC learning
- minimum ocv (pc) to start FCC learning
- minimum cycles to update fcc vs temp. table
2. New FCC is calculated using the cc count-
FCC_NEW = (cc_end - cc_start) / (soc2 - soc1)
cc_end = CC count when charing ends
cc_start = CC count when charging starts
soc1, soc2 = starting and ending SOC_rbatt value
3. Add a new sysfs entries to update the learnt fcc values
to userspace. These values are restored back on
reboot.
