Subject: [PATCH] [media] V4L2: em28xx: register a V4L2 clock source

Camera sensors usually require a master clock for data sampling. This patch
registers such a clock source for em28xx cameras. This fixes the currently
broken em28xx ov2640 camera support and can also be used by other camera
sensors.
