[media] tm6000: fix querycap and input/tuner compliance issues
- add device_caps support - fix bus_info - fix numerous tuner-related problems due to incorrect tests and setting v4l2_tuner fields to wrong values. - remove (audio) input support from the radio: it doesn't belong there. This also fixed a nasty issue where opening the radio would set dev->input to 5 for no good reason. This was never set back to a valid TV input after closing the radio device, thus leaving it at 5 which is out of bounds of the vinput card array.
