Redesign tuners struct for maximum flexibility

From: Michael Krufky <mkrufky@m1k.net>

- tunertype struct redefined to allow one or more tuner_params structs
  per tuner definition, one for each video standard.
- Each tuner_params struct has an element containing an arbitrary
  amount of tuner_ranges.
  (this is needed for dvb tuners - to be handled later)
- A tuner_range may be referenced by multiple tuner_params structs.
  There are many duplicates in here. Reusing tuner_range structs,
  rather than defining new ones for each tuner, will cut down on
  memory usage, and is preferred when possible.
- tunertype struct contains an element, has_tda988x.
  We must set this for all tunertypes that contain a tda988x
  chip, and then we can remove this setting from the various
  card structs.
- Improves tuners array memory usage efficiency.
- Right now, all tuners are using the first tuner_params[] array element
  for analog mode. In the future, we will be merging similar tuner
  definitions together, such that each tuner definition will have a
  tuner_params struct for each available video standard. At that point,
  the tuner_params[] array element will be chosen based on the video
  standard in use.
