pinctrl/nomadik: !CONFIG_OF build error

a60b57e "drivers/gpio: gpio-nomadik: Add support for irqdomains" broke
building with CONFIG_OF_GPIO disabled.

Without this patch, building nhk8815_defconfig results in:

/home/arnd/linux-arm/drivers/gpio/gpio-nomadik.c: In function 'nmk_gpio_probe':
/home/arnd/linux-arm/drivers/gpio/gpio-nomadik.c:1238:6: error: 'struct gpio_chip' has no member named 'of_node'
