[media] Move CI cxd2099 driver to staging
This driver is abusing the kernel<=>userspace API, due to the lack of a proper solution for it. A discussion were done at: http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html But there's not a solution for it yet. So, move the driver to staging, while we don't have a final solution. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
