ram: k3-ddrss: Set SDRAM_IDX using device private data, ddr_ram_size
The SDRAM_IDX in DDRSS_V2A_CTL_REG describes the number of address
bits minus 16 that are used to determine the mask used to detect
memory rollover and prevent aliasing and false coherency issues.
Set SDRAM_IDX using the device private data, ddr_ram_size for AM64x,
AM62x and AM62x SIP.
