syv682x: Support USB changer when VBUS status changes
When VBUS changes, the USB charger task needs to be notified. This CL
adds a flag to track the value of vbus so when it's checked, a change
in status can be determined.
BUG=b:113267982
BRANCH=none
TEST=Verfied that when external USB charger is connected/removed the
USB charger task gets notified with the new current state.
