Add support for the i.MX9 DDR controller, which has different register offsets and some function changes compared to the existing fsl_ddr controller. The ECC and error injection functions are almost the same, so update and reuse the driver for i.MX9. Add a special type 'TYPE_IMX9' specifically for the i.MX9 controller to distinguish the differences.
