hw/openrisc: Support monitor dumpdtb command
The openrisc machines don't set MachineState::fdt to point to their DTB blob. This means that although the command line '-machine dumpdtb=file.dtb' option works, the equivalent QMP and HMP monitor commands do not, but instead produce the error "This machine doesn't have a FDT". Set MachineState::fdt in openrisc_load_fdt(), when we write it to guest memory.
