of_gpio: should use new <linux/gpio.h> header

From: Wolfgang Grandegger <[email protected]>

Since commit 7560fa60fcdcdb0da662f6a9fad9064b554ef46c (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.
