target-ppc: Error out for -cpu host on unknown PVR
Previously we silently exited, with subclasses we got an opcode warning. Instead, explicitly tell the user what's wrong. An indication for this is -cpu ? showing "host" with an all-zero PVR. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Alexander Graf <agraf@suse.de>
