qcacmn: Process rx_mgmt_pkt based on frequency

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 part of above requirement add logic to process rx mgmt
packets based on the frequencies instead of channel numbers.
