Add the missing #include <linux/gpio/consumer.h> to fix this.

As the resulting driver won't work with GPIOLIB=n anyway, make DRM_PTN3460 depend on GPIOLIB || COMPILE_TEST.

Applied, thanks. Note that I dropped the part about adding the GPIOLIB dependency because that had been attempted previously to fix this, but it causes recursive dependencies on PowerPC (ppc64_defconfig). I don't know of a way to untangle those (I tried and failed miserably), so I think adding the include is really as good as it'll get.
