cfg/mac80211: add regulatory classes IE during TDLS setup
Seems Broadcom TDLS peers (Nexus 5, Xperia Z3) refuse to allow TDLS connection when channel-switching is supported but the regulatory classes IE is missing from the setup request. Add a chandef to reg-class translation function to cfg80211 and use it to add the required IE during setup. For now add only the current regulatory class as supported - it is enough to resolve the compatibility issue.
