chip/it83xx, it8xxx2: implement detect cc disconnection interrupt for SRC role
Implement detect cc disconnection interrupt for source. When TCPC
detect SNK/audio/debug device plug out (cc lines open), TCPC can
interrupt pd task to update cc state.
BUG=b:160548079
BRANCH=none
TEST=test on board reef_it8320, it81202_pdevb with TCPMv1, TCPMv2.
Connect to dongle, adapter and DRP, check
1.Plug in/out interrupt fire correctly.
2.Power role swap can state to SRC_READY and SNK_READY.
3.When partner disconnect, we discharge Vconn within
tVconnOFF(35ms).
