[ Upstream commit 6e031ec0e5a2dda53e12e0d2a7e9b15b47a3c502 ] Resolve build errors reported against UML build for undefined ioport_map() and ioport_unmap() functions. Without this config option a device cannot have vfio_pci_core_device.has_vga set, so the existing function would always return -EINVAL anyway.

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.
