imxv4l2src should be used with the NXP provided kernel.

v4l2src should be used with mainline kernel + mainline Gstreamer.

There is a recent series from Steve Longerbeam (still under
review/rework) that adds support for the camera capture on mx6 running
kernel 4.10-rc:

I was able to test his series with Gstreamer 1.10.2 using the standard
v4l2src plugin.
