[media] tea575x-tuner: update to latest V4L2 framework requirements
The tea575x-tuner module has been updated to use the latest V4L2 framework functionality. This also required changes in the drivers that rely on it. The tea575x changes are: - The drivers must provide a v4l2_device struct to the tea module. - The radio_nr module parameter must be part of the actual radio driver, and not of the tea module. - Changed the frequency range to the normal 76-108 MHz range instead of 50-150. - Add hardware frequency seek support. - Fix broken rxsubchans/audmode handling. - The application can now select between stereo and mono. - Support polling for control events. - Add V4L2 priority handling. And radio-sf16fmr2.c now uses the isa bus kernel framework.
