Device models aren't supposed to go on fishing expeditions for
backends. They should expose suitable properties for the user to set.
For onboard devices, board code sets them.
Device ssi-sd picks up its block backend in its init() method with
drive_get_next() instead. This mistake is already marked FIXME since
commit af9e40a.
Unset user_creatable to remove the mistake from our external
interface. Since the SSI bus doesn't support hotplug, only -device
can be affected. Only certain ARM machines have ssi-sd and provide an
SSI bus for it; this patch breaks -device ssi-sd for these machines.
No actual use of -device ssi-sd is known.
