A Xen PVH domain doesn't have a PCI bus or devices, so it doesn't need PCI support built in. Currently, XEN_PVH depends on XEN_PVHVM which depends on PCI. Introduce XEN_PVHVM_GUEST as a toplevel item and change XEN_PVHVM to a hidden variable. This allows XEN_PVH to depend on XEN_PVHVM without PCI while XEN_PVHVM_GUEST depends on PCI. In drivers/xen, compile platform-pci depending on XEN_PVHVM_GUEST since that pulls in the PCI dependency for linking.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
