Subject: [PATCH v2] MAINTAINERS: refurbish SWIOTLB SUBSYSTEM sections after refactoring

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 contain the architecture-independent
pieces for swiotlb, but leave the small architecture-dependent pieces to
the architecture 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.

v1: https://lore.kernel.org/lkml/20220601075613.28245-1-lukas.bulwahn@gmail.com/
v1 -> v2:
  addressed Christoph's comment, removed arch/*/kernel/pci-swiotlb.c
  added Juergen's ack

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