qcacmn: Select best candidate at first connection

Ver a proveniência 
Best candidate at first connection is a mechanism
to select best possible candidate for making Wi-Fi
connection based on the scan results provided.
Driver use Scan results to calculate score for each
BSS and select the best candidate to connect.

This enhances the user experience by connection
to better AP, based on certain parameters.
