John Baldwin 0d95597ca9 Use a more proper fix for enabling HT MSI mapping windows on Host-PCI 
bridges.  Rather than blindly enabling the windows on all of them, only
enable the window when an MSI interrupt is enabled for a device behind
the bridge, similar to what already happens for HT PCI-PCI bridges.

To implement this, each x86 Host-PCI bridge driver has to be able to
locate it's actual backing device on bus 0.  For ACPI, use the _ADR
method to find the slot and function of the device.  For the non-ACPI
case, the legacy(4) driver already scans bus 0 looking for Host-PCI
bridge devices.  Now it saves the slot and function of each bridge that
it finds as ivars that the Host-PCI bridge driver can then use in its
pcib_map_msi() method.

This fixes machines where non-MSI interrupts were broken by the previous
round of HT MSI changes.
