boot: Pass the correct FDT to the EVT_FT_FIXUP event

Now that we support multiple device trees with the ofnode interface, we
can pass the correct FDT to this event. This allows the 'working' FDT to
be fixed up, as expected, so long as OFNODE_MULTI_TREE is enabled.

Also make sure we don't try to do this with livetree, which does not
support fixups yet.
