The generic PCI host driver relies on MSI domains for MSIs to be provided to its end-points. Make this dependency explicit. This cures the warnings occuring on arm/arm64 VMs when booted with PCI virtio devices and no MSI controller (no GICv3 ITS, for example). It is likely that other drivers will need to express the same dependency.

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.
