driver/tcpm/it8xxx2: turn both cc pins off when disable Vconn
If the pd port has previous connection and supplies
Vconn, then RO jumping to RW reset the system,
we never know which cc is the previous Vconn pin,
so we always turn both cc pins off when disable
Vconn power switch.
This change is leveraged from it83xx (CL:3178341),
although Vconn is controlled by ppc on asurada series
and asurada series don't happen the bug, but we still
need this change for the future that if there is a
project control Vconn by GPIO.
BUG=none
