Currently, Dynamic Frequency Selection (DFS) and its related radar events
are supported only for non-MLO case where deflink (or link_id 0) is always
considered. However, with MLO in place, there is need to handle DFS in
per-link manner instead of always handling it on per device.

Add support to handle DFS interference related events per-link basis.
