Added device_is_agp callback to drm_driver. This function is called by the platform-specific drm_device_is_agp function. Added implementation of this function the the Linux-specific portion of the MGA driver to detect PCI G450 cards. Added code to the Linux-specific portion of the generic DRM layer to not initialize AGP infrastructure if the card is not AGP (this matches what already existed in BSD). Fix up i810/i830 and i915 drivers to always return AGP as they don't always report the capability. Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI bridge.
