qcacld-3.0: Don't add duplicate frequencies in pcl list

Currently if SCC frequencies are added in pcl list and
rest 5GHz frequencies are required to be added with lesser
weightage then all 5GHz/6GHz frequencies are added including
SCC channels. so in pcl duplicate entries are found for SCC
frequencies with different weightage.

Fix is not to add SCC frequencies during addition of 5GHz/6GHz
frequencies if SCC frequencies are already present in pcl.
