GPIO fixes for the v3.13 series:

- Fix compile warnings.

- Fix overly talkative diagnostic messages from usual use
  cases wrt GPIO descriptors.

- Add a documentation 00-INDEX

- Use platform GPIOs as fallback when ACPI or device tree is
  used as the primary means to get GPIO lines.

- A bug fix for the MPC8572/MPC8536 fixing erroneous input data.

gpiolib: change a warning to debug message when failing to get gpio

It's the drivers responsibility to react on failure to get
the gpio descriptors and not the frameworks. Since there are
some common peripherals that may or may not have certain
pins connected to gpio lines, depending on the platform,
printing the warning there may end up generating useless bug
reports.
