This moves the calibration hardware code specific to AR5008,
AR9001 and AR9002 to its own set of files. To make things easier
to read and maintain we split the calibration hardware code into
two files, one for generic calibration routines and another for
the settings used for the three different types of calibration
supported:
* IQ calibration
* ADC gain calibration
* ADC-DC calibration
Each of these have their own respective collection routine
and calibration routines.
To get do all this we move power amplifier calibration
code to its own helper, ath9k_hw_pa_cal(). I noticed that
ath9k_hw_pa_cal() checks for a skip on calibration, but during
ar9002_hw_init_cal(), which is called upon reset we don't check
for a skip. We'll need to review that further.
