changes since v1:

- add comments from Grant Likely <grant.likely@secretlab.ca>
  use mpc5200_defconfig as default configuration, therefore added
  SIMPLE_GPIO support in it, because this is not selectable as a
  module.
- add comments from Wolfram Sang <w.sang@pengutronix.de>
- rebase against current next

changes since v2:
- add comment from Wolfram Sang
  remove unofficial binding
