qcacmn: Enable 160 MHz Spectral scan in QCN9000

Till IPQ8074/IPQ8074_V2 each Spectral detector was capable of
doing scan up to 80 MHz. But in QCN9000 each Spectral detector
is capable of doing scan up to 160 MHz. As a result there will
be only one Spectral report in 160/80p80 MHz. Modify Spectral
Rx path to support single Spectral report in 160 MHz.
