[PATCH] mac80211: deprecate RX status noise

[Johannes Berg <johannes@sipsolutions.net>]

The noise value as is won't be used, isn't
filled by most drivers and doesn't really
make a whole lot of sense on a per packet
basis -- proper cfg80211 survey support in
mac80211 will need to be different.

Mark the struct member as deprecated so it
will be removed from drivers.

I'll make patches for drivers when it becomes
clear that it won't clash with any work others
have pending.
