The exti layer now allows drivers to register interrupt callbacks during board initialization. All details of the driver using a particular EXTI pin have been removed from the EXTI layer so it can now be used on any board without board-specific modification. This includes some nice refinements provided by Mike Smith during initial review. His original commits have been squashed into this one.
