Boten: Use cached Vbus presence for Vbus check
Use the TCPCI driver cached Vbus presence when checking for Vbus. This
avoids unnecessary TCPC wakes when tasks are querying our Vbus presence.
BRANCH=None
BUG=b:178173274
TEST=on boten, watch EC console and observe TCPC does not show repeated
wakeups when C0 is in low power mode
