[media] v4l2: use new flag to enable core priority handling
Rather than guess which driver supports core priority handling, require drivers
that do to explicitly set the V4L2_FL_USE_FH_PRIO flag in video_device.
Updated the core prio handling accordingly and set the flag in the three
drivers that do.
