qcacmn: Address incorrect radarfound frequency computation

In Pebble (11BE qcn6432 chip), the radar-found frequency is
incorrectly computed in the current implementation as
dfs_translate_radar_params is executed.
The translation function (dfs_translate_radar_params) which 
alters the frequency offset is needed for pre-11BE chipsets.
For 11BE chips where
wmi_service_radar_found_chan_freq_eq_center_freq
service is advertised by HALPHY, the frequency translation is not
needed as the offset sent by FW in wmi_dfs_radar_detection_event_id
can be directly used.
