    mac80211: ath11k: restore 160MHz support
    
    Recent ath11k sync introduced a regression causing 80+80 and 160MHz to
    stop being advertised and thus not selectable due to the respective feature
    flags being cleared.
    
    So, until we get answers upstream to what was the reasoning behind this and
    it gets fixed, lets just remove the flag clearing to reanable 160MHz.

+Subject: [PATCH] wifi: ath11k: restore 160MHz support
+
+The blamed commit started clearing 80+80 and 160MHz support flags for 5G.
+This is preventing those modes from being advertised and thus used causing
+a regression, so until this is properly sorted out lets remove the flag
+clearing to restore 160MHz support.
