mac80211: Add support for connection quality monitoring
Add support for the set_cqm_config op. This op function configures the
requested connection quality monitor rssi threshold and rssi hysteresis
values to the hardware if the hardware supports
IEEE80211_HW_SUPPORTS_CQM.
For unsupported hardware, currently -EOPNOTSUPP is returned, so the mac80211
is currently not doing connection quality monitoring on the host. This could be
added later, if needed.
