power: lc709203f: adjust the SoC based on platform specific need
Sometimes platform needs to adjust the SoC reporting to framework
based on battery its use and parameter programmed on the FG.
Adjust SoC read from device to 0 to 100% before reporting to framework
based on (minimum_soc, maximum_soc) possible on that platform.
