commit eb12c957735b582607e5842a06d1f4c62e185c1d upstream.
It's the last user, and more importantly, it's the last non-legacy user of anything in drm_pci.c.
The only tricky bit is the agp initialization. But a close look shows that radeon does not use the drm_agp midlayer (the main use of that is drm_bufs for legacy drivers), and instead could use the agp subsystem directly (like nouveau does already). Hence we can just pull this in too.
A further step would be to entirely drop the use of drm_device->agp, but feels like too much churn just for this patch.
