linux-v4l2: Add auto reset on timeout option

Adds frame time multiple based timeout option, instead of the hardcoded
1 second timeout.

Adds optional automatic device stream reset when the device times out.
Helps with devices that "lock up" or "freeze", for example Magewell and
Elgato USB HDMI capture devices.

The automatic reset is by default off and optional. Turning it on can
cause issues for devices that work but drop a lot of frames.
