qcacld-3.0: Convert channel to frequency in rx mgmt handler

As a part of 802.11ax amendment, 6GHz band operation is added.

Since the 6 GHz channel numbers are overlapping with existing 2.4GHz
and 5GHz channel numbers, use frequency to identify unique channel
operation instead of channel number. Channel frequency is unique across
bands.

As a part of above requirement, in the existing WMI interface handlers
and related functions, wherever missing, add frequency attributes to
identify unique channel operation.
