Thomas Zimmermann ff28a9f8d3 drm: Inline AGP wrappers into their only callers
The AGP wrapper functions serve no purpose. They used to handle
builds that have CONFIG_AGP unset. But their callers are all in
drm_agpsupport.c, which only gets build with CONFIG_AGP.

v2:
	* clarify CONFIG_AGP in commit description (Daniel)
