The AR9100 at least doesn't have an external serial EEPROM attached to the MAC; it instead stores the calibration data in the normal system flash. I believe earlier parts can do something similar but I haven't experienced it first-hand. This commit introduces an eepromdata pointer into the API but doesn't at all commit to using it. A future commit will include the glue needed to allow the AR9100 support code to use this data pointer as the EEPROM.
