Add resolution and fps on mfw_v4lsrc

Browse Source 
Add support for changing resolution and frame rate with mfw_v4lsrc.
This is essential for embedded applications that are not happy with
the default VGA@30.

This makes constructs like the following functional on devices like
i.MX6 with MIPI cameras:

Camera { viewfinder { resolution: "320x240"; maximumFrameRate: 15 } }
