it83xx/gpio: disable unused cc port module
To prevent cc pins leakage and cc pins can be used as gpio.
We will check if the chip supported tcpc physical port count is
more than board active ITE port count. If yes, we will disable
unused cc port module.
BUG=none
BRANCH=none
TEST=1) on board it8xxx2_pdevb with chip it81202, check the pd
port connection with adapter and dongle when hibernate
and resume.
adapter: connect
dongle: disconnect then re-connect
2) on board it83xx_evb with chip it8320, set cc pins as
gpio, check output level when hibernate and resume.
