wlan: Set TxBF csn value based on ini configuration.

Broadcom AP has an issue that when pronto advertise the csn value
as 3 it uses the 2 antenna in the NDPA packet but it suppose to
use the 3 antenna in the NDPA packet. If we advertise the csn value
as 2 then it uses 3 antenna in the NDPA packet. We need to have
ini configuration for setting the csn value.
