qcacld-3.0: Consolidate DS mode definitions

The file cds_ieee80211_common.h contains a large number of macros that
are used to describe most fields in IEEE 802.11 frames. Despite that,
currently WMA has an enum ds_mode to represent the Distribution System
Mode settings. In order to avoid unnecessary duplicate definitions
remove enum ds_mode and instead use the cds_ieee80211_common macros.
