SWDEV-78052 - [CQE-OCL][DTB][QR][LNX]RQ conf test "Multiple device context" fails in few asics due to CL#1196902
	- Restore synchronization on the DMA engine. OCL doesn't require a sync, because resource isn't busy on the CAL device. However without sync there are less CBs available. Conformanace multidevice test will create around 60 queues, instead of 70
