qcacld-3.0: Add support for FT over DS

Add support to enable the "FT over DS" via
QCA_WLAN_VENDOR_ATTR_CONFIG_FT_OVER_DS vendor config
command.
This configuration helps the firmware to support
“FT over DS” instead of “FT over Air”

Change-Id: I493bf15f83bc39135aaeefa9d8ef328f0fc0cda3
CRs-Fixed: 2968680
