qcacmn: Populate pdev secondary_cur_chan_list for mobile device SAP

secondary_cur_chan_list channel list is for mobile device SAP, which
by default cannot enable on LPI channels, and cannot enable on SP
channel until AFC server response received.

Populate 6 GHz channels to secondary_cur_chan_list based on 6 GHz
regulatory rules of current country, LPI channel will not be added
in because it is not allowed for mobile SAP. And update 6 GHz SP
channel attributions if received AFC response.

Also add APIs to populate power attributions of secondary_cur_chan_list
and decide proper 6 GHz power attributions if 6 GHz channel frequency
and bandwidth being selected.
