Dedede: Check versus vSinkDisconnect on VBUS_REMOVEDstabilize-13505.1.B-master
For variants using the charger Vbus ADC, add a check versus
vSinkDisconnect to determine if the TC layer connection has been broken.
BRANCH=None
BUG=b:168831161
TEST=on waddledee, confirm we can reliably source 5V from a charger
without erroneously detecting disconnect
