Add a new hostapd_is_dfs_overlap() helper function to DFS module. This function tells whether the selected frequency range overlaps with DFS channels in the current hostapd configuration. Selected frequency reange is specified by its center frequency and bandwidth. Signed-off-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com>
