mmal/deinterlace: Add option to use QPUs for advanced deinterlace
The image_fx deinterlace filter can optionally make use of the VideoCodre Quad
Processor Units to deinterlace higher resolution content with an advanced
algorithm than the Video Processor Unit can handle. As the QPUs are used for
OpenGL as well this shares performance with other tasks. Leave the option
disabled by default as it will easily raise performance issues if the system
is doing other tasks besides video playback in parallel.
