qcacld-3.0: Extend force 1x1 ini

Browse Source 
Currently the driver checks whether the device
supports antenna sharing, and if the AP is added
in the OUI framework, then the driver modifies the
nss value to 1 to avoid sending SMPS to the peer AP.
Now suppose the device does not support Antenna sharing,
but supports DBS and is helium HW, then going to DBS HW
mode would result in peer sending a SMPS frame to the peer
as the helium HW only has two antennas, and one is needed
by each MAC now.

Fix is to add a third param in force 1x1 ini which would
decide the driver should consider the antenna sharing as
mandatory or not.
