ath9k_hw: Fix RTT calibration
This patch fixes multiple issues with the current RTT implementation in ath9k. * The data that is obtained from the RTT interface registers are stored in 31:5 - mask out the extra bits when reading them. * A history buffer is maintained which is not needed at all. Remove this array and just store the baseband data for each chain (or bank). * A 'num_readings' variable was being used to handle the last entry. But it was being used in an improper manner, with the result that the RTT values were never being written to the RTT Interface registers. Fix this by using a simple flag. * Stop baseband operations before programming the calibration values to the HW. * Do not restore RX gain settings as part of RTT.
