waddledee: Use VBUS ADC for extpower
There's an issue with the CHG_DET bit which was causing the AC change
notifications to not occur. This commit replaces the usage of the
CHG_DET bit with reading the VBUS ADCs to determine VBUS presence.
BUG=b:161269327
BRANCH=None
TEST=Build and flash waddledee rev 1, verify AC notification changes
work as expected.
