currently we have multiple #ifdef CONFIG_PCI_IOV blocks spread over different compliation units and headers, all dealing with SR-IOV specific behavior. This violates the style guide which discourages conditionally compiled code blocks and hinders maintainability by speading SR-IOV functionality over many files. Let's move all of this into a conditionally compiled pci_iov.c file and local header and prefix SR-IOV specific functions with zpci_iov_*.
