The unflattened devicetree structure is available to be used not long
after the page tables have been set up on most architectures, and is
available even before that on other architectures.

Hence, move the call to fdt_init_reserved_mem() to after
unflatten_device_tree() is called so that the reserved memory nodes can
be accessed using the unflattened device tree APIs.

Using the unflattened devicetree APIs is more efficient than using the
flattened devicetree APIs.
