The device_state module is used for debouncing GPIO inputs to
determine device state. It was overkill for managing the battery
present state as forwarded to the write protect pin, and split that
handling between 3 files (board.c, wp.c, device_state.c). Move all of
that logic into wp.c so it's easier to maintain.
BUG=none
BRANCH=cr50
TEST=manual
plug in battery (or ground DIOM2)
wp command reports WP enabled
unplug battery (or pull DIOM2 high)
wp command reports WP disabled
