V4L/DVB (4451): MT2060: IF1 Offset from EEPROM, several updates

Browse Source 
- AGC gain set to 3
- The tuning sequence has been changed to match the DibCom driver ( from I2C
  spy captures )
- For LITE-ON adapters : The IF1 frequency is now tuned according to the
  calibration values stored in EEPROM.
