char/agp: Disable frontend without CONFIG_DRM_LEGACY
It's probably full of bugs ready for exploiting by userspace. And
there's not going to be any userspace for this without any of the drm
legacy drivers enabled too. So just couple it together.
Note that the frontend is only the /dev/agp ioctl interface, which per
Adam is only used by the i810 userspace drivers. All other drivers go
through the drm bufmap agp handling abstraction apparently.
v2: Augment commit message a bit from m-l feedback.
