hw/ppc: set machine->fdt in xilinx_load_device_tree()
This will enable support for 'dumpdtb' QMP/HMP command for the virtex_ml507 machine. Setting machine->fdt requires a MachineState pointer to be used inside xilinx_load_device_tree(). Let's change the function to receive this pointer from the caller. kernel_cmdline' can be retrieved directly from the 'machine' pointer. 'ramsize' wasn't being used so can be removed. Cc: Edgar E.
