s390/pci: base support
Add PCI support for s390, (only 64 bit mode is supported by hardware): - PCI facility tests - PCI instructions: pcilg, pcistg, pcistb, stpcifc, mpcifc, rpcit - map readb/w/l/q and writeb/w/l/q to pcilg and pcistg instructions - pci_iomap implementation - memcpy_fromio/toio - pci_root_ops using special pcilg/pcistg - device, bus and domain allocation Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
