From: Yi Min Zhao <zyi...@linux.ibm.com>
QEMU on s390 supports PCI multibus since forever. But zPCI, as extension
of PCI device on s390, is the significant capability. Only when zPCI
capability is existing, we consider QEMU supports PCI multibus properly.
So let enable PCI multibus only if zPCI is supported.
