Trogdor: Assert a GPIO to turn off rails before enter hibernate
We disabled the PSL mode hibernate. We uses another GPIO to control
switches, which were originally controlled by PSL_OUT. Add this GPIO,
named HIBERNATE_L, such that the non-PSL mode hibernate can retrofit
the original design.
BRANCH=None
BUG=b:169797080
TEST=Triggered EC hibernate and checked the HIBERNATE_L GPIO asserted.
