spapr: add dumpdtb support
dumpdtb (-machine dumpdtb=<file>) allows one to inspect the generated
device tree of machine types that generate device trees. This is
useful for a) seeing what's there b) debugging/testing device tree
generator patches. It can be used as follows
$QEMU_CMDLINE -machine dumpdtb=dtb
dtc -I dtb -O dts dtb
