xen: fixes for 5.3-rc3

It contains:
- a small cleanup
- a fix for a build error on ARM with some configs
- a fix of a patch for the Xen gntdev driver
- 3 patches for fixing a potential problem in the swiotlb-xen driver
  which Konrad was fine with me carrying them through the Xen tree

Thanks.


Juergen
