[PULL 1/1] device_tree: Add info message when dumping dtb to file

Subject: [PULL 1/1] device_tree: Add info message when dumping dtb to file

From: Leonardo Bras <address@hidden>

When dumping dtb to a file, qemu exits silently before starting the VM.

Add info message so user can easily track why the proccess exits.
Add error message if dtb dump failed.
