arm64: zynqmp: Fix the memory node for k26/k24 kria som boards
PMUFW requires top 1MB of the lower DDR memory reserved for its operation,
this is missing in k26/k24 sm static dts files because of which U-Boot
throws warning messages "efi_free_pool: illegal free" as EFI puts
some code to that space which shouldn't happen.
