media: uvcvideo: Allow custom control mapping

Browse source

Some advanced controls might not be completely implemented by vendors.

If the controls are a enumeration, UVC does not gives a way to probe
what is implemented and what is not.

Let's create a new callback function where heuristics can be implemented
to detect what is implemented and what not and update the control
mapping accordingly.
