qcacmn: Populate DFS_CFREQ2 and BW-NSS mapping

Make the following TLV WMI layer changes related to 160/80+80 MHz
functionality:
  - While forming the VDEV start/restart command, if the request from
    the upper layer indicates the dfs_set_cfreq2 flag, then enable the
    WMI_CHAN_FLAG_DFS_CFREQ2 channel flag. This is needed in order to
    enable radar event reporting for the secondary 80 MHz segment.
    Make this change only in the WIN specific implementation of
    copy_channel_info(). If required for MCL, to be handled separately.
  - Move the 'peer_bw_rxnss_override' member in
    'struct peer_assoc_params' to outside the '#ifndef CONFIG_MCL'
    section so that it is available both on MCL and WIN. Since
    in MCL code peer_assoc_params is initialized to all zeros and
    peer_bw_rxnss_override is not set anywhere later, this should
    have no side effects.
  - While forming the PEER assoc completion command, populate the
    peer_bw_rxnss_override field as per the corresponding parameter
    sent by the upper layer. This is required for providing override
    values of Rx NSS for bandwidths higher than 80 MHz.

Testing:
   - Tested on QCA8074 that the WMI_CHAN_FLAG_DFS_CFREQ2 channel flag
     is being set in the VDEV start command if the secondary 80 MHz
     lies on DFS channels (tried VHT160 and VHT80_80)
   - Tested on QCA8074 AP and STA that the peer_bw_rxnss_override
     value is being set in the PEER assoc completion command to
     indicate Rx NSS value 2, when NSS value 4 is used for <=80 MHz
     (tried VHT160 and VHT80_80). Also tested ping.
