endeavour: gpios: USB-C polarity and PSE reset
The polarity gpio is used to detect the USB-C plug orientation since
Endeavour does not have a PD controller. This will be read using
ectool by the factory test.
The PSE controller reset signal was moved from PLTRST to an EC gpio
output. Not currently used since we reset using an I2C register.
BUG=b:157236750, b:156399232
TEST=ectool gpioget USB_C0_POL_L, EC_RST_LTC4291_L
BRANCH=none
