drm: call drm_gem_object_funcs.mmap with fake offset
The fake offset is going to stay, so change the calling convention for drm_gem_object_funcs.mmap to include the fake offset. Update all users accordingly. Note that this reverts 83b8a6f242ea ("drm/gem: Fix mmap fake offset handling for drm_gem_object_funcs.mmap") and on top then adds the fake offset to drm_gem_prime_mmap to make sure all paths leading to obj->funcs->mmap are consistent. v3: move fake-offset tweak in drm_gem_prime_mmap() so we have this code only once in the function (Rob Herring).
