V4L/DVB (5311): Tda1004x driver updates

There are the following changes:
- separate configuration of IF and GPIOs.
- set GPIOs before firmware load. This helps to avoid I2C address
  collisions.
- if desired invert GPIOs at sleep (automatic return to analog mode of card).
- added 3 tuner configuration bytes to config stuct.
- added i2c gate address to config struct.
- moved _state struct declaration to header file to make it accessible
  on board layer.
- added "conf_probed" to the state struct to allow i.e. probing for correct
  tuner version.
- changed firmware load mechanism to always:
  + check if already loaded
  + try to boot from eeprom
  + try downlad from host
- corrected name of tda10046 firmware image (backward compatible).
