Pull GPIO fixes from Linus Walleij:
 "Two fixes. They are both kind of important, so why not send a pull
  request on christmas eve.

   - Fix a build problem in the gpio single register created by
     refactorings.

   - Fix assignment of GPIO line names, something that was mangled by
     another patch"
