ath9k_hw: Cleanup TX power calculation for AR9287
* Add a few comments, and move the updation of max_power_level
to a helper routine. This is also done by non-4K based chipsets,
this will be fixed in a separate patch.
* Remove two WARs which are required for old AR5416 chipsets,
and are not needed for AR9287.
* Fix indentation and make things readable.
