Commit 28ec711 (drm/agp: move AGP cleanup paths to drm_agpsupport.c)
broke the build for platforms which do not have AGP since it moved the
AGP cleanup code inside an #ifdef __OS_HAS_AGP which are referenced
unconditionally in drm_drv.c.  This causes build failures for embedded
SoCs which use DRM but do not have AGP.

Fix this by providing stub static inlines in the header.
