b24413180f ("License cleanup: add SPDX GPL-2.0 license identifier to
files with no license") added SPDX GPL-2.0 to several PCI files that
previously contained no license information.
Add SPDX GPL-2.0 to all other PCI files that did not contain any license
information and hence were under the default GPL version 2 license of the
kernel.

This PCI host bridge from V3 Semiconductor needs no further
introduction. An ancient driver for it has been sitting in
arch/arm/mach-integrator/pci_v3.* since before v2.6.12 and the
initial migration to git.
But we need to get the drivers out of arch/arm/* and get proper handling of
the old drivers, rewrite and clean up so the PCI maintainer can control the
mass of drivers without having to run all over the kernel. We also switch
swiftly to all the new infrastructure found in the PCI hosts as of late.
Some code is preserved so I have added an extensive list of authors in the
top comment section.
This driver probes with the following result:
