Eric Anholt d450e052dc Add support for G965/Q965/GM965/GME965/GME945 AGP. 
This adds a function to agp.c to set the aperture resource ID if it's
not the usual AGP_APBASE.  Previously, agp.c had been assuming
AGP_APBASE, which resulted in incorrect agp_info, and contortions by
agp_i810.c to work around it.

This also adds functions to agp.c for default AGP_GET_APERTURE() and
AGP_SET_APERTURE(), which return the aperture resource size and disallow
aperture size changes.  Moving to these for our AGP drivers will likely
result in stability improvements.  This should fix 855-class aperture
size detection.

Additionally, refuse to attach agp_i810 when some RAM is above 4GB and
the GART can't reference memory that high.  This should be very rare.
The correct solution would be bus_dma conversion for agp, which is
beyond the scope of this change.  Other AGP drivers could likely use
this change as well.

G33/Q35/Q33 AGP support is also included, but disconnected by default
due to lack of testing.
