[PATCH] GPIO Driver Sample Application

[Gedare Bloom]

Try to figure out how to make the sample not be BSP (BBB)-specific. If
you can't then instead this should probably go into examples-v2 and
use a similar model as the LED example there. Speaking of which,
perhaps the LED example should be extended to be supported on the BBB?
