This prevents QEMU from creating devices underneath us, which can change
across QEMU versions (see de875be20ca66). To prevent this in the future,
add '-nodefaults' for all invocations of QEMU, not just powerpc64le.
Tested with QEMU 3.1.0, 4.2.0, and 5.0.0-rc2.
NOTE: This is the only architecture that we actually set devices for so
this should be a no-op for everything else but we might add other
devices in the future.
