When 'bad_data_bit' is less than 32, 'bad_data_bit - 32' becomes negative, and left-shifting by a negative value in C is undefined behavior. Fix this by combining 'cap_high' and 'cap_low' into a 64-bit variable.

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.

The ECC and error injection functions are almost the same, so update and reuse the driver for i.MX9. A special type 'TYPE_IMX9' is added specifically for the i.MX9 controller to distinguish the differences.
