xen/pci-swiotlb: reduce visibility of symbols
xen_swiotlb and pci_xen_swiotlb_init() are only used within the file
defining them, so make them static and remove the stubs. Otoh
pci_xen_swiotlb_detect() has a use (as function pointer) from the main
pci-swiotlb.c file - convert its stub to a #define to NULL.
