The 4 GiB boundary is at 0xffffffff+1 , not at 0x80000000, fix this.
The PHYS_SDRAM of i.MX8M is at 0x40000000 , so to restrict ram_top
below 4 GiB, the ram_top has to be set to 0xffffffff as it is not
an offset from the start of PHYS_SDRAM, but rather a physical address
marking the topmost allowed DRAM address.
Fixes: e27bddff4b9 ("imx8m: Restrict usable memory to space below 4G
boundary")
