ath5k: Increase PHY settling parameters for turo mode

* On turbo mode increase PHY settling times, note that
 we only increase switch settling time on AR5212 as indicated
 by initvals.

 * A few cleanups: Move frame control settings for AR5210 from
 reset_tx_queue to tweak_initvals and remove phy_scal settings
 from tweak_initvals (we tweak them alread on set_sleep_clock).
