ath5k: Small cleanup on tweak_initvals 

* Now that we properly set rx/tx latencies for AR5311 remove
 that old buggy part of code left inside ath5k_hw_tweak_initval_settings
 that was never executed (you can't have an RF5112 radio on a mac older
 than AR5212). Also use a magic value for 5311 PHY_SCAL value.
