qcacmn: 6g scan optimizations based on the ini

Browse Source 
Below optimizations can help to improve 6g scan,
1. RNR-only: Consider only 6g RNR(PSC and non-PSC) channels found
   while scanning 2g and 5g bands, as the 6g APs are likely to
   present in RNR channels.
2. Duty cycle: There is a chance to miss the standalone 6g APs as
   they don't advertise RNR IEs. So, instead of optimizing all
   scan requests, we can consider to do a full scan with duty
   cycle(n) where optimization is skipped for every nth full scan.
   The full scan requests 1 to n-1 are going to be optimized as
   per RNR-only policy.
Driver shall maintain a scan count to track the full scans and
decides whether to optimize the scan (scan count 1 to n-1) or
send it as it is(scan count n) to firmware.
