char/agp: Remove frontend code
The AGP subsystem supports a user-space interface via /dev/agpgart. It
is only enabled with DRM support for mode setting in user space. (i.e.,
CONFIG_DRM_LEGACY). All of that DRM code has been removed and the option
will go away. Hence remove the AGP frontend.
Modern DRM drivers with kernel mode setting handle AGP support internally.
