wl1271: add workaround to avoid distortion due to excessive tx power
Luciano Coelho [Mon, 12 Oct 2009 12:08:44 +0000 (15:08 +0300)]
We still don't have proper calibration for our devices, so we are using way
too much power for TX, which causes a lot of distortion.  This hack hardcodes
the txpower to 7dBm.
