trogdor: Change GPIO HIBERNATE_L to open drain
We stuffed an external pull-up resistor on the GPIO HIBERNATE_L for
fixing the CCD bugs, like b/173828265, b/177611071.
The GPIO can be used as open drain.
BRANCH=Trogdor
BUG=b:189184814
TEST=Tested on Lazor; CCD connection still worked under EC hibernate.
