Since we are not going to be exporting HT40-/+
flags for now through nl80211 we supply the channel
flags as a whole through debugfs so users/testers can
see whether or not HT40-/+ is allowed.
Screenshot on channel 1 (2.412 GHz):
[root@pogo ~]# mount -t debugfs debugfs /debug/
[root@pogo ~]# cat /debug/ieee80211/phy0/ht40minusallowed
0
[root@pogo ~]# cat /debug/ieee80211/phy0/ht40plusallowed
1
[root@pogo ~]# umount /debug
