I never was able to find out proper way to measure noise with wl1251.
The algorithm I came up and included in this patch is most likely
incorrect. But as having support for noise survey doesn't do any harm,
and hopefully we even might motivate someone to fix the algorithm, I
think it's safe to have this patch.
