qcacld-3.0: Use frequency based api to set channel params

Currently when driver receives CSA, it uses channel number based
api to fill the channel params which does not work for the 6GHz
channels and may give incorrect results, which may result in
unexpected behavior.

To address above issue use frequency based api to set channel
params which gives correct results for all the bands.
