media: v4l2-dev/ioctl: Add V4L2_CAP_IO_MC

Browse Source 
Add a video device capability flag to indicate that its inputs and/or
outputs are controlled by the Media Controller instead of the V4L2 API.
When this flag is set, ioctl for enum inputs and outputs are
automatically enabled and programmed to call a helper function.
