p54: fix rssi auto calibration

p54: fix rssi auto calibration

Ever wondered why the signal was so bad with p54 compared to madwifi, or intel?

Well, if you have revision 1 rssi calibration curve points in your EEPROM, then wonder no more.
The firmware wants a extra 1 byte padding for every curve point. But someone forgot to put
them into the EEPROM's data structure...

So now, big question: what happens when we blindly "memcpy" these data points?
