[media] cxd2820r: use static GPIO config when GPIOLIB is undefined
It is fallback condition as GPIOLIB seems to be disabled by default. Better solution is needed, maybe GPIOLIB could be enabled by default? Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
