Jan Beulich e243ae953b PCI: only build xen-pcifront in PV-enabled environments
The driver's module init function, pcifront_init(), invokes
xen_pv_domain() first thing. That construct produces constant "false"
when !CONFIG_XEN_PV. Hence there's no point building the driver in
non-PV configurations.

Drop the (now implicit and generally wrong) X86 dependency: At present,
XEN_PV can only be set when X86 is also enabled. In general an
architecture supporting Xen PV (and PCI) would want to have this driver
built.

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.
