cfg80211: return channel noise via survey API
This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
ops that a driver can implement. The goal of this command is to allow a
drivers to report channel survey data (e.g. channel noise, channel
occupation).
For now, only the mechanism to report back channel noise has been
implemented.
In future, there will either be a survey-trigger command --- or the existing
scan-trigger command will be enhanced. This will allow user-space to
request survey for arbitrary channels.
Note: any driver that cannot report channel noise should not report
any value at all, e.g. made-up -92 dBm.
