coral: Enable CONFIG_BATTERY_LEVEL_NEAR_FULL for LED function
coral: Enable CONFIG_BATTERY_LEVEL_NEAR_FULL for LED function

When the battery gets to returns the FULL flag, bd99956 charging is
disabled and battery learning is enabled. This state will remain until
the FULL flag is cleared by the battery. The original fix had this
level at 97%, but on the various batteries tested this appears to
happen at 95%. The CONFIG_BATTERY_LEVEL_NEAR_FULL allows an adjustment
for this level and is only used for LED states.

BUG=b:64192049
BRANCH=None
TEST=Manual Let system charge to 100% when FULL flag is set in the
battery, verified the LED was in correct state. Then let battery drain
until the FULL flag is clear and observe that the battery requests
charge current. The LED stays in the expected full charge state.
