The LED gpio is incorrectly programmed for AR9300 and so the led
is not working propelry. AR93xx uses gpio 10 for LED and not the
default.

Hw next tigger time is configured as current_tsf + (timer_period * 10) which
is wrong, it should be current_tsf + timer_period. The wrong hw timer configuration
would cause btcoex related issues.

AR9485 doesn't use the default GPIO pin for LED and GPIO 6 is actually
used for this.

Remove ath/debug.h and the includes of these files.
Coalesce long formats.
Correct a few misspellings and missing "\n"s from these logging messages.
Remove unnecessary trailing space before a newline.
Remove ARRAY_SIZE casts, use printf type %zu

When the timer_next argument to ath9k_gen_timer_start is behind the tsf value,
tsf + timer_period is used, which is what ath_btcoex_period_timer was setting
it to.

OProfile showed that ath9k was spending way too much time in
ath9k_hw_set_interrupts. Since most of the interrupt mask changes only
need to globally enable/disable interrupts, it makes sense to split
this part into separate functions, replacing all calls to
ath9k_hw_set_interrupts(ah, 0) with ath9k_hw_disable_interrupts(ah).

ath9k_hw_set_interrupts(ah, ah->imask) only gets changed to
ath9k_hw_enable_interrupts(ah), whenever ah->imask was not changed
since the point where interrupts were disabled.

Some vendors require the LED to be ON always irrespective of any
radio activity. Introducing a module parameter to disable blinking,
so that one can choose between always on or led blink during
activity.

As all bt packets are priority traffic during bt scan, wifi
will get disconnected when bt scan lasts for few seconds. Fix
this by allocating 10% of bt period time (4.5ms) to wifi fully.
