pd: Mark VBUS as present when power swapping from source to sink
If we power swap from a source to a sink and begin charging, VBUS will
never be marked as present, which has bad side-effects when VBUS
disappears and we wish to stop charging.
BUG=chrome-os-partner:36389
TEST=Manual on Samus. Connect Samus-to-Samus and initiate charge
override on the port. Verify that charging from the port begins. Unplug
the cable and verify that the in-OS charge icon disappears. Repeat 10x.
BRANCH=Samus
