mac80211: add a flag to indicate CCK support for HT clients 

commit 2dfca312a91631311c1cf7c090246cc8103de038 upstream.

brcm80211 cannot handle sending frames with CCK rates as part of an
A-MPDU session. Other drivers may have issues too. Set the flag in all
drivers that have been tested with CCK rates.

This fixes a reported brcmsmac regression introduced in
commit ef47a5e4f1
"mac80211/minstrel_ht: fix cck rate sampling"
