[PATCH] MAINTAINERS: refurbish SWIOTLB SUBSYSTEM sections after refactoring

[Lukas Bulwahn]

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.

Update the SWIOTLB SUBSYSTEM to include arch/x86/kernel/pci-dma.c, which
contains the swiotlb setup now and drop the file pattern that does not
match any files.

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.

Christoph, please pick this minor non-urgent clean-up patch for swiotlb.

I think this file is better left for the x86 maintainers.
