This commit enables the PSL pins for zoombini. Previously, we were initializing the PSL_OUT pin to high, but it actually turns out that setting the output from a 0 to a 1 indicates that the firmware wants to remove Vcc1. This caused the EC to not boot up. This commit removes the improper initialization of the GPIO and additionally sets up the hibernate wake pins accordingly such that they can be used by the PSL glue logic. BUG=b:65647213 BRANCH=None TEST=Flash zoombini without rework. Verify board comes up okay. TEST=Enter `hibernate` on console; Verify board goes to sleep. Verify that each hibernate wake pins wakes up the board successfully.
