Add F_MMU_IN_ORDER_WR_EN_MASK and F_MMU_STANDARD_AXI_MODE_EN_MASK definitions in MISC_CTRL register. F_MMU_STANDARD_AXI_MODE_EN_MASK: If we set F_MMU_STANDARD_AXI_MODE_EN_MASK (bit[3][19] = 0, not follow standard AXI protocol), the iommu will priorize sending of urgent read command over a normal read command. This improves the performance. F_MMU_IN_ORDER_WR_EN_MASK: If we set F_MMU_IN_ORDER_WR_EN_MASK (bit[1][17] = 0, out-of-order write), the iommu will re-order write commands and send the write commands with higher priority. Otherwise the sending of write commands will be done in order. The feature is controlled by OUT_ORDER_WR_EN platform data flag.
