	 * Force all Normal memory transactions from ISO and non-ISO to be
	 *     non-coherent(bypass ROC, avoid cache snoop to avoid perf hit).
	 * Force the SO_DEV transactions from ordered ISO clients(EQOS) to
	 *     non-coherent path and enable MC PCFIFO interlock for ordering.
	 * Force the SO_DEV transactions from ordered non-ISO clients (PCIe,
	 *     XUSB, SATA) to coherent so that the transactions are
	 *     ordered by ROC.
	 * PCFIFO ensure write ordering.

	 *     go through ROC ordering.
	 * Ordering enable for Read clients is not necessary.
	 * R5's and A9 would get necessary ordering from AXI and

	 *     - MMIO ordering is through dev mapping and MMIO
	 *       accesses bypass SMMU.
	 *     - Normal memory is accessed through SMMU and ordering is
	 *       ensured by client and AXI.
	 *     - Ack point for Normal memory is WCAM in MC.
	 *     - MMIO's can be early acked and AXI ensures dev memory ordering,
	 *       Client ensures read/write direction change ordering.
