RSSI reported by the RX descriptor requires little manipulation.
Manipulate and report the correct RSSI to the stack. This will
fix the improper signal levels reported by iwconfig iw dev wlanX
station dump. Also the Link Quality reported seems to be varying
(falls to zero also sometimes) when iperf is run from STA to AP.
Also use the default noise floor for now as the one reported
during the caliberation seems to be wrong.

in progress from STA to AP)

This patch fixes a bug in ath9k_hw_init_cal() where the wrong
calibration was being done for non-AR9285 chipsets.
Also add a few helpful comments.

This patch cleans up the functions dealing with calibration,
using proper return values.
ath9k_hw_per_calibration(), ath9k_hw_calibrate now return bool values
instead of setting error values in the function arguments.

ADC gain calibration has to be done for all non 2GHZ-HT20 channels.
