qcacmn: Refine chirp check for ETSI type 4 radar

Browse Source 
Currently if the delta peak of the ETSI type 4 radar pulse is 0, it will
be considered as radar false dection, which affects normal dfs ETSI type
4 certification test.

More checks are added when delta peak of the ETSI type 4 radar pulse is 0.
If psidx_diff, the difference in the FFT peak index between the short FFT
and the first long FFT, is greater than 4 and less than 16, it is still
considered as valid ETSI type 4 radar pulse.
