Daniel Henrique Barboza bf353ad555 qmp/hmp, device_tree.c: introduce dumpdtb
To save the FDT blob we have the '-machine dumpdtb=<file>' property.
With this property set, the machine saves the FDT in <file> and exit.
The created file can then be converted to plain text dts format using
'dtc'.

There's nothing particularly sophisticated into saving the FDT that
can't be done with the machine at any state, as long as the machine has
a valid FDT to be saved.

The 'dumpdtb' command receives a 'filename' parameter and, if the FDT is
available via current_machine->fdt, save it in dtb format to 'filename'.
In short, this is a '-machine dumpdtb' that can be fired on demand via
QMP/HMP.

This command will always be executed in-band (i.e. holding BQL),
avoiding potential race conditions with machines that might change the
FDT during runtime (e.g. PowerPC 'pseries' machine).
