qcacmn: Populate supported FFT sizes for Beryllium Spectral

Beryllium chipsets support FFT sizes as follows for different sscan widths.
    20MHz:-   Min FFT size: 5, Max FFT size: 9
    40MHz:-   Min FFT size: 5, Max FFT size: 10
    > 40MHz:- Min FFT size: 5, Max FFT size: 11
Populate these FFT sizes for Beryllium targets.
