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

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 tested this rework on a i.mx8mm-evk.
