When a device passes through the video data while still having its own
receiver and transmitter, it can use the same frequency as the upstream
link does. The Intel MEI CSI device is an example of this. An integer menu
control isn't useful in conveying the actual frequency to the receiver in
this case.
Document that the LINK_FREQ control may also be a 64-bit integer control.
