qcacmn: Add Function pointer to Enable/Disable BW_Expand

When BW Expansion feature is enabled using UCI or cfg80211tool
command, the utility function to set/get the BW Expand feature
is introduced inside DFS module.

A new dfs member dfs_use_bw_expand is used to store the status
of BW Expansion feature.
