from Beryllium onwards a single Flow Search Table will be used across multiple radios. to ensure this a single FST attach is called for the first SOC's pdev and FST detach is called only during last pdev of last SOC. the same FST instance is saved in all pdevs of all the SOCs CRs-Fixed: 3366409 Change-Id: I42fbdc6f09fb902021877e100a2831a1a24bc975
