[PATCH v5 4/9] ram: k3-ddrss: Setup ECC region start and range

[Santhosh Kumar K]

Setup the ECC region's start and range using the device private data,
ddrss->ddr_bank_base[0] and ddrss->ddr_ram_size. Also, move start and
range of ECC regions from 32 bits to 64 bits to accommodate for
DDR greater than or equal to 4GB.
