58b5e4c731 ath9k: Move processing of FFT frames to different functions
Since more checks and fixes will be added later and ath_cmn_process_fft is
already big enough.

e33f855d43 ath9k: Fix hanlding of maximum magnitude index
Maximum magnitude index is a 5bit signed integer,
convert to an 8bit signed integer and then "shift" it so that it can be used
as an array index. Note that the current implementation adds +1 to the index
value (so it can't be used as an array index) and it's only valid for HT20
channels.

Note that the maximum magnitude index is not being used by
the userspace tools that parse FFT samples (they just use
maximum magnitude) so this doesn't break userspace compatibility.

2eaea3284b ath9k: common-spectral: don't depend from ATH9K_DEBUGFS
we can have here two variants. Add
ATH9K_CMN_DEBUGFS y if ATH9K_CMN_DEBUGFS || ATH9K_HTC_DEBUGFS
wich will add more configurations and testcases. Or remove ATH9K_HTC_DEBUGFS
which need more time to be done.

So, make common-spectral ignore ATH9K_DEBUGFS option for now.
