media: uvcvideo: Probe the PLF characteristics

Browse source

The UVC 1.5 standard defines 4 values for the PLF control: Off, 50Hz,
60Hz and Auto. But it does not clearly define if all the values must be
implemented or not.

Instead of just using the UVC version to determine what the PLF control
can do, probe it.
