cfg80211: extend range deviation for DMG
Recently, DMG frequency bands have been extended till 71GHz, so extend the range check till 20GHz (45-71GHZ), else some channels will be marked as disabled. Signed-off-by: Chaitanya Tata <Chaitanya.Tata@bluwireless.co.uk> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
