Similar to [1], declare this dependency for PCI probe in ACPI based
flow.

This is required especially for RISC-V platforms where MSI controller
can be absent.

It would be better to refer to this as 9ec37efb8783 ("PCI/MSI: Make
pci_host_common_probe() declare its reliance on MSI domains") instead
of a link to the mailing list archives.

The git SHA1 is part of the git repo, and git can tell us where that
SHA1 is included.  The lore URL is external and doesn't say anything
about what happened to the patch.
