Wolfgang Grandegger 18ad7a61e1 of_gpio: Should use new <linux/gpio.h> header
Since commit 7560fa60fc (gpio: <linux/gpio.h>
and "no GPIO support here" stubs) drivers can use GPIOs if they're available,
but don't require them.

This patch actually enables this feature.

Anton Vorontsov 863fbf4966 [POWERPC] OF helpers for the GPIO API
This implements various helpers to support OF bindings for the GPIO
LIB API.

Previously this was PowerPC specific, but it seems this code isn't
arch-dependent anyhow, so let's place it into of/.

SPARC will not see this addition yet, real hardware seem to not use
GPIOs at all. But this might change:

"16-bit I/O port" sounds promising. :-)
