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.
