Storo: Use display SoC to control charge LED
Currently, Storo uses the state of charge provided from the battery.
This isn't the same as the SoC shown on the screen because Powerd
compensates it based on the full factor and the low battery shutdown
threshold.
This change makes Storo use the display SoC for the charge LED module
so that the charge LED and the display SoC synchronously work.
BUG=b:181506409
BRANCH=dedede
TEST=Storo's LED turns from amber to white when the display soc
reaches 95% (internally 94.6%).
