6be0323d97 pci_setup_intr() will only enable MSI/MSI-X for direct children. Add methods
to vga_pci.c to request on behalf of it's children.  This causes vgapci to show
up as the interrupt owner in vmstat -i, rather than the child device.

e7e2941b81 Allow child devices of vgapci(4) to query VPD strings and use MSI/MSI-X
interrupts.  For the MSI/MSI-X case, we only allow 1 child device to use
MSI or MSI-X at a time.

cb46523df0 Don't add an agp child in vgapci's attach routine if the PCIY_AGP
capability is present as not all devices supported by the agp_i810 driver
(such as i915) have the AGP capability.  Instead, add an identify routine
to the agp_i810 driver that uses the PCI ID to determine if it should
create an agp child device.

8e8e46ccfc Add a vgapci(4) stub device driver for VGA PCI devices. This device serves
as a bus so that other drivers such as drm(4), acpi_video(4), and agp(4)
can attach to it thus allowing multiple drivers for the same device.  It
also removes the need for the drmsub hack for the i8[13]0/i915 drm and agp
drivers.

bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.
