Log:
Relax the check for a PCI-express chipset by assuming the system is a
PCI-express chipset (and thus has functional MSI) if there are any
PCI-express devices in the system, not requiring a root port device.
With PCI-X the chipset detection has to be very conservative because there
are known systems with PCI-X devices that do not appear to have PCI-X
chipsets. However, with PCI-express I'm not sure it is possible to have
a PCI-express device in a system with a non-PCI-express chipset. If we
assume that is the case then this change is valid. It is also required
for at least some PCI-express systems that don't have any devices with
a root port capability (some ICH9 systems).
