ath5k: Simplify cw_min/max and AIFS configuration
Get rid of overly complicated cw_min/max and AIFS configuration:
* Validate values in ath5k_hw_set_tx_queueprops(), so we can use them directly
without further checks or computation in ath5k_hw_reset_tx_queue().
* Simplifiy by using AR5K_TUNE_AIFS|CWMIN|CWMAX variables directly since we
don't support XR or B channels. That way we can also remove
AR5K_TXQ_USEDEFAULT and the confusing logic around it.
* Update data types: AIFS is u8, CW's are u16.
* Remove now unneeded variables in ath5k_hw.
