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).
