commit 8a3bddf67ce88b96531fb22c5a75d7f4dc41d155 upstream.

This doesn't do anything except auto-init drm_agp support when you
call drm_get_pci_dev(). Which amdgpu stopped doing with

    drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev

No idea whether this was intentional or accidental breakage, but I
guess anyone who manages to boot a this modern gpu behind an agp
bridge deserves a price. A price I never expect anyone to ever collect
:-)
