[PATCH] arm64: fix endianness annotation in get_kaslr_seed()

In the flattened device tree format, all integer properties are
in big-endian order.
Here the property "kaslr-seed" is read from the fdt and then
correctly converted to native order (via fdt64_to_cpu()) but the
pointer used for this is not annotated as being for big-endian.
Fix this by declaring the pointer as __be64 instead of u64.
