The PCI bus helper is the only user of it. Call it directly before
device-registration to get rid of the callback.
Note that all drm_agp_*() calls are locked with the drm-global-mutex so we
need to explicitly lock it during initialization. It's not really clear
why it's needed, but lets be safe.
v2: Rebase on top of the agp_init interface change.
v3: Remove the rebase-fail where I've accidentally killed the ->irq_by_busid
callback a bit too early.
