revert changes, this needed to be done differently.

fix linking of DRMKMS kernel.
XXX: apple does not compile!

Revert "normalization" for now.

branches: 1.6.34;
Add support agp_amd64. Imported from FreeBSD.

branches: 1.5.4; 1.5.8;
add very experimental Apple UniNorth AGP driver

branches: 1.4.26; 1.4.30; 1.4.32; 1.4.34;
merge ktrace-lwp.

branches: 1.3.12;
add centralized {eisa,isa,pci,agp,mca}busprint() functions which do
what tens of the bus' parents foo{...}bridge_print()s scattered around do

branches: 1.2.2; 1.2.4; 1.2.8; 1.2.24;
Give each AGP controller its own attribute, and let the "agpbus"
device (rather, the device that carries that attribute) also
carry one or more attributes indicating which type of controller
it might be.

This will allow systems that might have AGP, but would never have
e.g. an Intel PCI-Host bridge, to trim out code that won't be used.

Move the AGP device declaration stuff into files.agp.
