Commit 78013eaadf69 ("x86: remove the IOMMU table infrastructure")
refactored the generic swiotlb/swiotlb-xen setup into pci-dma.c, but
misses to adjust MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about
broken references.
As only include/linux/swiotlb.h is unique to the SWIOTLB SUBSYSTEM section
and Christoph is maintainer of DMA MAPPING HELPERS and SWIOTLB SUBSYSTEM,
just merge those two sections.
Leave the small architecture-dependent pieces to the arch maintainers.
Further, update the XEN SWIOTLB SUBSYSTEM to include all swiotlb-xen
headers and replace the pattern in drivers with the specific one file that
matches this pattern.
