Drivers have no business looking into dma-mapping internals and check
what backend is used. Unfortunstely the DRM core is still broken and
tries to do plain page allocations instead of using DMA API allocators
by default and uses various bandaids on when to use dma_alloc_coherent.

Hi all,
this little series removes the last swiotlb API exposed to modules.

Remove the dangerous late initialization of xen-swiotlb in
pci_xen_swiotlb_init_late and instead just always initialize
xen-swiotlb in the boot code if CONFIG_XEN_PCIDEV_FRONTEND is enabled.

Move the exact checks when to initialize the Xen swiotlb code out
of pci_xen_swiotlb_init and into the caller so that is uses readable
positive checks, rather than negative ones that will get even more
confusing with another addition.
