Noise floor stopped being available as part of scan results quite some
time ago with mac80211-based drivers and wpa_supplicant does not
currently receive it with nl80211 at all. It might still be possible to
get it with other driver interfaces (with non-mac80211 drivers)..

In other words, dropping it from the D-Bus API for scan results may not
change that much at this point. Anyway, I do want to get wpa_supplicant
supporting the new survey commands in nl80211 to get the per-channel
noise floor information (and some other statistics like TX/RX use). This
should also be made available through the new D-Bus API.
