ath5k: use noise calibration from madwifi hal
This updates ath5k to calibrate the noise floor similar to the way it is done in the madwifi hal and ath9k. Of note: - we start NF measurement at the same time as AGC calibration, but do not actually read the value until the periodic (long) calibration - we keep a history of the last few values read and write the median back to the hardware for CCA - we do not complain if NF calibration isn't complete, instead we keep the last read value.
