board: ti: am62x: Account for DDR size fixups if ECC is enabled
Call into k3-ddrss driver to fixup device tree and resize
the available amount of DDR if ECC is enabled.
A second fixup is required from A53 SPL to take the fixup
as done from R5 SPL and apply it to DT passed to A53 U-boot,
which in turn passes this to the OS.
