Since, not every board may have all memory channels configured and all available banks of DMC used, we wish to refactor configs for Memory Bank size and numbers as per board memory config. For Example, Peach-Pit has 2GB memory and will be using only 4 banks but Peach-Pi has 3.5GB memory and will be using all 7 available SDRAM banks.
