6ec414fd12 ath9k: make ath_mci_duty_cycle static 
This fixes this sparse warning:

  CHECK   drivers/net/wireless/ath/ath9k/mci.c
drivers/net/wireless/ath/ath9k/mci.c:23:4: warning: symbol 'ath_mci_duty_cycle' was not declared. Should it be static?

8a30930563 ath9k_hw: make bluetooth coexistence support optional at compile time 
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.

This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.

On MIPS this reduces the total size for the modules by about 20k.

d2182b69dc ath: Convert ath_dbg(bar, ATH_DBG_<FOO>, to ath_dbg(bar, FOO 
Add ATH_DBG_ to macros to shorten the uses and
reduce the line count.

Coalesce ath_dbg formats.
Add missing spaces to coalesced formats.
Add missing newline terminations to ath_dbg formats.
Align ath_dbg arguments where appropriate.
Standardize ath_dbg formats without periods.

7dc181c273 ath9k: Add btcoex profile management support for AR9462 
AR9462 chips have the capabilities to provoide bluetooth
profile information. For non-AR9462 btcoex chips, the BT
priority traffic was identified by periodically polling
the respective registers and updated dutycycle, stomptype,
etc. As AR9462 chip offers the BT profile informations,
let us make use of that to update aggregation limit,
dutycycle, stomptype and wieghtages.
