tcpmv2: make connect after auto-toggle driver specific
nct38xx needs to have the cached polarity set in order
to leave DRP mode without going back to an OPEN line.
Other TCPCI implementations break when this happens.
So moved it to a driver specific function instead
TODO(b/149415919): Consider trying to clear the DRP
mode instead of changing the polarity
BUG=b:149311437
BRANCH=none
TEST=verify charger functions on Trogdor
