V4L/DVB (10758): cx18: Convert I2C devices to v4l2_subdevices
This is a major perturbation to cx18 I2C device handling to convert it to the v4l2_device/subdeivce framework. This change breaks GPIO audio multiplexer control for the time being. It will be fixed in a coming change. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
