It was used as an option to turn CONFIG_XEN_PCI
and CONFIG_SWIOTLB_XEN and .. um, I think that are the ones.

And the XEN_PCI_FRONTEND would select this which in turn would activate
the CONFIG_SWIOTLB_XEN and CONFIg_XEN_PIC.

At least that is what it used to be at some point. I think in my merge
trees I don't have that anymore but they are still present in Jeremy's.
