hibernate: Re-init GPIO levels on hibernate wake
Reset-on-hibernate wake performs a soft-reset, which re-initializes GPIO
states to ROM POR values. Therefore, it is necessary to re-init GPIO
states once again based on board-level GPIO settings.
BUG=chrome-os-partner:58077
BRANCH=gru
TEST=Run `hibernate` on gru, wake, then run `bd99955_dump`. Verify
actual register values are printed rather than zeros.
