Right now, all devices use bus 0 for eeprom. However,
it seems that newer versions of Terratec H6 uses a different
buffer for eeprom.
So, add support to use a different I2C address for eeprom and
add a new card ID for the board described at:
http://forum.kodi.tv/showthread.php?tid=312902
PS.: This patch was meant to allow testing the device. It may
be wrong or incomplete, as it doesn't attempt to set GPIOs.
