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.
