EDAC/fsl_ddr: Add support for i.MX9 DDR controller

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.
