ath5k: Use helper function to get eeprom mode from channel
Introduce a helper function to get the EEPROM mode from channel and remove multiple similar switch statements. Also since it's now easy to get the EEPROM mode from the channel, use them inside the functions which need it, instead of passing a redundant ee_mode parameter.
