[PATCH] gpio: delay: add OF_GPIO dependency

[Arnd Bergmann <arnd@xxxxxxxxxx>]

From: Arnd Bergmann <arnd@xxxxxxxx>

The new driver fails to build when OF_GPIO is disabled:

drivers/gpio/gpio-delay.c: In function 'gpio_delay_of_xlate':
drivers/gpio/gpio-delay.c:79:39: error: 'struct gpio_chip' has no member named 'of_gpio_n_cells'

Fixes: cf5dec80c4e23 ("gpio: Add gpio delay driver")
