Subject: [PATCH] ath5k: More EEPROM code updates

* Don't scale power values on RF5111 EEPROMs because they get out of bounds (power is u8, so multiplying power by 50 is too much and there is no
reason to do so -we don't do it on other chips anyway-). HAL does it as a technique to handle 0.5 dbm steps but i believe it's not the right thing to
do and certainly not the right place to do it. We 'll work this out on interpolation code for all chips (0.5 or 0.25 steps etc) in a generic way.
