Even if it ends up being the board code using these APIs it seems
sensible to have a standard API that GPIO drivers can use to expose the
functionality.  This will help with getting control into code Linux owns
(since people don't have to implement custom APIs) and will mean we can
do things like add control of this for device tree based boards.
