ram: k3-ddrss: Introduce ECC Functionality for full memory space
Introduce ECC Functionality for full memory space as implemented in the
DDRSS. The following is done to accomplish this:
* Introduce a memory region "ss" to allow dt to provide DDRSS region,
which is not the same as "ctl" which is the controller region.
* Introduce a "ti,ecc-enable" flag which allows a memorycontroller
instance to enable ecc.
* Introduce functionality to properly program the DDRSS registers to
enable ECC for the full DDR memory space if enabled with above flag.
* Expose a k3_ddrss_ddr_fdt_fixup call to allow fixup of fdt blob to
account from DDR memory that must be reserved for ECC operation.
