Yes, indeed. I added a new enum value for that:
NL82011_SEC_CHAN_NO_HT = no HT (this is the default if
	NL80211_ATTR_WIPHY_SEC_CHAN_OFFSET is not included)
NL80211_SEC_CHAN_DISABLED = HT20 only
NL80211_SEC_CHAN_BELOW = HT40-
NL80211_SEC_CHAN_ABOVE = HT40+

The driver will then get hw.conf.ht.{enabled,sec_chan_offset} with the
needed information.
