Import portions of the PowerPC OF PCI implementation into new file "ofwpci.c", common for other platforms. The files ofw_pci.c and ofw_pci.h from sys/powerpc/ofw no longer exist. All required declarations are moved to sys/dev/ofw/ofwpci.h. This creates a new ofw_pci_write_ivar() function and modifies some others methods. Most functions contain existing ppc implementations in the majority unchanged. Now there is no need to have multiple identical copies of methods for various architectures.
