When inductive charging just starts, there might be a blip on
CHARGE_DONE signal and it'd cause our charging control logic to shut
down charging. Fix this by waiting for a second before we start
monitoring CHARGE_DONE.
Also, once we see CHARGE_DONE=1 and disable charging, CHARGE_DONE will
go low. Handle this by ignoring all subsequent CHARGE_DONE change until
the next time the lid is opened.
BRANCH=Ryu
BUG=None
TEST=Pass the updated unit test.
TEST=Charge a base on Ryu P3.
