[U-Boot] Bug: boot_fdt_add_mem_rsv_regions() can drop upper 32 bits of physical addresses

When phys_addr_t is 32 bits wide, boot_fdt_add_mem_rsv_regions() implicitly uses only the low 32 bits of each memory reservation's address and length to determine what to reserve. So, for example, an FDT memory reservation like
/memreserve/ 0x180000000 0x40000000;
will actually reserve physical memory starting at 0x80000000, not 0x180000000 (though the printf() will claim it is reserving starting at 0x180000000).
