s390/pci: add sparse annotations 

Fix the following warnings from the sparse code checker:

arch/s390/include/asm/pci_io.h:165:49: warning: cast removes address space of expression
arch/s390/pci/pci.c:476:44: warning: cast removes address space of expression
arch/s390/pci/pci.c:491:36: warning: incorrect type in argument 2 (different address spaces)
arch/s390/pci/pci.c:491:36:    expected void [noderef] <asn:2>*addr
arch/s390/pci/pci.c:491:36:    got void *<noident>
