ath5k: Set turbo bit on rf bank 2
* A diff between rfbuffer settings of turbo and non-turbo
modes indicates there is a bit on bank 2 related to turbo operation
(it's set on turbo modes). This bit is present on all radios except
RF5413 that seems to have a completely different bank 2. Also
since 2317 has the same rf-registers locations with 2425 and
since the bit exists on 2317 I assume it also exists on 2425/2417).
So in case we use turbo mode (40MHz) enable it on bank modification.
