Subject: [PATCH v2 4/6] dt-bindings: memory: fsl: Add compatible string
nxp,imx9-memory-controller
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.
