Quackingstick: fix hibernate behavior for rev1
The power of hall sensor and the LID_OPEN_EC on rev1 are
different, and it cause LID_OPEN_EC wake the EC immediately
when EC enter hibernate.
Remove GPIO_LID_OPEN from hibernate_wake_pins for
board_id <= 1 to let rev1 dut can enter hibernate.
Rev1 needs the workaround for ACOK can't go High to wake EC up.
Set GPIO_HIBERNATE_L always open-drain.
BUG=none
BRANCH=trogdor
TEST=Rev1 dut can enter hibernate
