ath9k: add noise floor override option
Introduce a debugfs option to manually override the noise floor,
ignoring the automatically tuned noise floor of the driver/hw.
In my tests with a AR9580 based module and a tx99 5 MHz interferer,
I could tune the noisefloor to -95 dBm or above to allow communication
again. The automatic noise floor calibration sometimes could adapt to
the situation as well, but not reliably and permanently.
I would consider this "feature" experimental and interesting for people
debugging the noise floor calibration or other effects of the hardware.
