gpio: GPIO_GRGPIO should depend on OF

While the Aeroflex Gaisler GRGPIO driver has no build-time dependency on
gpiolib-of, it supports only DT-based configuration, and is used only on
DT systems.  Hence add a dependency on OF, to prevent asking the user
about this driver when configuring a kernel without DT support.
