wireless: deprecate WDS and disable by default
The old WDS 4-addr frame support is very limited, e.g. * no encryption is possible on such links * it cannot support rate/HT/VHT negotiation * management APIs are very restricted These make the WDS legacy mode useless in practice. All of these are resolved by the 4-addr AP/client support, so there's also no reason to improve WDS in the future. Therefore, add a Kconfig option to disable legacy WDS. This gives people an "emergency valve" while they migrate to the better-supported 4-addr AP/client option; we plan to remove it (and the associated cfg80211/mac80211 code, which is the ultimate goal) in the future.
