qcacld-3.0: Modify logic to associate with HT clients

Browse source 
Add the following rules when HT client is associating with SAP,
1.2G-AS platform: SAP associates with HT (11n) clients as 2x1 in 2G
and 2X2 in 5G.
2.Non-2G-AS platform: SAP associates with HT (11n) clients as 2X2
in 2G and 5G and async DBS scan is disabled.
3.5G-AS platform: SAP associates with HT (11n) clients as 2X2 in 2G
and 5G and async DBS scan is disabled.
