charger: Add state for discharge + full
When battery is fully charged, Reef starts discharging to protect
battery and starts charging again when charge level goes down
around 95%. To prevent the battery LED from showing blue with the
charger plugged in, this patch adds a new state for discharge +
nearly full. Reef shows a color indicating battery is full if
an external charger is present.
BUG=b:35775017
BRANCH=none
TEST=Fully charge Electro. Plug in OEM charger. LED lights blue.
