[PATCH] DT: kirkwood: Fix Openblock A6 external GPIO pins

[Jason Cooper]

By assigning the pin hog to the pinctrl node, we correctly configure the
MPPs.  However, they are not available to userspace.

Fix this by assigning the hogs to the gpio node.

After this, the following works as expected:

  # echo 28 >/sys/class/gpio/export
  # echo low >/sys/class/gpio/gpio28/direction

After sleeping on it a night, I decided to leave the dip switches alone.
