Since, an AP may have any combinations of DA,PO, and FO chips on it,
having support for all chips always is redundant. Therefore, enable the
chip specific code as and when required.
DA:- Direct attach
PO:- Partial offload
FO:- Full offload
WLAN_DFS_DIRECT_ATTACH :- enable/disable DA specific DFS code.
WLAN_DFS_PARTIAL_OFFLOAD :- enable/disable PO specific DFS code.
WLAN_DFS_FULL_OFFLOAD :- enable/disable FO specific DFS code.
