Subject: [PATCH 5/9] microblaze: Use NULL as the default DTB

early_init_dt_scan() now takes care of falling back to the built-in DTB,
and printing what it did.

Note: I did not remove the now-unused fdt parameter from
      machine_early_init(), as this would require quite some changes
      to head.S. BTW, cmdline is also unused.
