iMX9 memory controller is similar with other layerscape chips. But some register layout has a little bit difference, so add new compatible string 'nxp,imx9-memory-controller' for it. imx9 need two 'reg', one for DDR controller and the other is ECC inject engine register space. Keep the same restriction for other compatible string.
