cfg80211: check radar interface combinations
To ease further DFS development regarding interface combinations, use the interface combinations structure to test for radar capabilities. Drivers can specify which channel widths they support, and in which modes. Right now only a single AP interface is allowed, but as the DFS code evolves other combinations can be enabled.
