mb/google/octopus: Update the PEN_EJECT GPIO configuration
PEN_EJECT GPIOs are active high and also require an internal pull-up.
Update the GPIO configuration appropriately.
BRANCH=octopus
BUG=b:117953118
TEST=Ensure that the system boots to ChromeOS. Ensure that the stylus
tools open on pen eject. Ensure that the system can enter S0ix and S3
states successfully when the pen is inserted. Ensure that the system
wakes on Pen Eject. Ensure that the system does not enter S0ix and S3
states when the pen is placed in its holder. Ensure that the
suspend_stress_test runs successfully for 25 iterations with the pen
placed in its holder.
