gpio: intel-mid: lock IRQs when starting them
This uses the new API for tagging GPIO lines as in use by IRQs. This enforces a few semantic checks on how the underlying GPIO line is used. ChangeLog v1->v2: - Explicitly call the - empty - mask/unmask functions from the startup/shutdown hooks. These are currently empty, but maybe they will not be that forever, so better be safe than sorry.
