tcpm/it83xx: use PD_VCONN_SWAP_DELAY delay time for Vconn drop 

The Vconn doesn't drop to 0v before we disable 5v tolerant on cc,
so I use the already existent baseboard configuration
PD_VCONN_SWAP_DELAY to increase delay time for Vconn drop.

BUG=none
BRANCH=none
TEST=on drawcia, Vconn drop to 0v before we disable 5v tolerant on cc.
