xen: branch for v5.15-rc2

It contains:
- The first hunk of a Xen swiotlb fixup series fixing multiple minor
  issues and doing some small cleanups
- Some further Xen related fixes avoiding WARN() splats when running
  as Xen guests or dom0
- A Kconfig fix allowing the pvcalls frontend to be built as a module

Thanks.

Juergen
