Scan the tree for reserved memory before unflattening it. As Rob
Herring said:
| These should be reversed. early_init_fdt_scan_reserved_mem() works on
| the flat tree. Reserved memory needs to be reserved before
| unflatten_device_tree() starts allocating memory. Though I imagine that
| doesn't really matter for UML.

Add a dtb=<filename> option to boot UML with a devicetree blob. This
can be used for testing driver code using UML.
