qcacld-2.0 to qcacld-3.0 propagation
Currently driver populates default supported and extended supported
rates in beacons even if hostapd.conf file wants to change
supported and extended supported rates.
Fix this by parsing beacon head and tail to get supported
and extended rates and populate them in sap config.
If Driver force acs is enabled, driver acs will get priority.
In case of driver based acs, driver should
ignore basic and extended rates from hostapd.conf and should
populate default rates.
