[PATCH v2 00/10] Fix gpio-hogs and sync with Linux gpiolib

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Quoting v1:

  the purpose of this series is to fix the gpio-hogs mechanism since this
  is broken since commit 3641d381e6 ("gpiolib: Add of_xlate support").
  
  Patch1: Revert the above mentioned commit to make the gpio-hogs working
          again.
  
  Patch2-10: Add the of_xlate support required for the upcoming sunxi
             pinctrl driver. The mechanism is now more in sync with kernel
             gpiolib. This allows to sync easier with the kernel gpiolib
             in case of new features or fixes.

I've incorporated feedback and tested this still works on a i.mx8mn.
Patch 1 should be ok to go into master and the rest to next IMO.

Changelog in each patch.
