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. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
