ath9k: Display calibration data piers in debugfs

Browse Source 
Display per frequency calibration data in dump_modal
debugfs entry including reference power, voltage,
tx temperature and noise floor.

Example of chain 0 of OEM card (dump from modal_eeprom):
Chain 0
Freq	 ref	volt	temp	nf_Cal	nf_Pow	rx_temp
5180	-30	0	137	0	0	0
5320	-24	0	137	0	0	0
5500	-15	0	137	0	0	0
5620	-10	0	137	0	0	0
5700	-15	0	137	0	0	0
5745	-16	0	135	0	0	0
5785	-19	0	136	0	0	0
5825	-22	0	136	0	0	0
