split static functions in pci_host.h into pci_host.c and pci_host_template.h. Later a structures declared in pci_host.h, PCIHostState, will be used. However pci_host.h doesn't allow to include itself easily. This patches addresses it. pci_host.h includes functions which are instantiated in .c by including pci_host.h with typedefing pci_addr_t. pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio or target_phys_addr_t for mmio in .c file. That prevents from including pci_host.h to use PCIHostState because of requiring type, pci_addr_t. Its purpose to include is to instantiate io function for mmio or ioio depending on which pci host bridge requires ioio or mmio. To avoid including code, we always instantiate both version.
