qcacmn: Modify hal_rx_radiotap_num_to_freq for 6G frequencies

Browse Source 
When an AP operates on a 6G channel. The channel frequency in the
radiotap header, in the beacon frame, shows an incorrect 6G frequency.

This is because, the function hal_rx_radiotap_num_to_freq is not updated
to handle the 6G channelization spec update ( IEEE 802.11 11AX Draft 6.1).

To fix this issue, update the function hal_rx_radiotap_num_to_freq to
handle the 6G channelization spec update (increase the 6G frequencies by
an offset of 10MHz).
