8edb254c8c ath9k: use ath9k_hw_fbin2freq instead of FBIN2FREQ
The FBIN2FREQ macro and the ath9k_hw_fbin2freq function
does the same thing. Remove the macro, and use the inline
function instead.

6010e72cdf ath9k: merge power correction constants

Both reduction and increase must use the same value, so

21bd6ea311 ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAIN
The REDUCE_SCALED_POWER_BY_THREE_CHAIN symbol is
defined in different eeprom files, and the value
varies between the different files.

In eeprom_def.c and in ar9003_eeprom.c the value
of the symbol is 9, however the comments in these
files indicates the value should be 10*log10(3)*2
which is 9.54242509439325. Replace the the value
to 10 in these files.

f58cc809d2 ath9k_hw: Remove BTCOEX initvals
The MAX_TXPWR table for BTCOEX is not needed for AR9462.
Programming these values to the HW results in undesirable
behavior - for example, large number of delimiter/data
underruns are seen in AES-CCMP mode. Also, registers like
AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX
power table is programmed to the HW, and frames being transmitted
end up being looped back to the RX engine, an example being beacon
frames in IBSS mode.

Remove this table for now - this fixes CCMP performance and general
IBSS usage.

This adds a DFS pattern detector to ath9k. It is fed with pulse events
by the radar pulse detector and reports in place whether a pattern
was detected. On detection, the result is reported as radar event to
the DFS management component in the upper layer.

Currently the ETSI DFS domain is supported with detector lines for
the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP
will be added gradually.

To include the pattern detector, ath9k must be built with support
for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).
