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).
Fixes: 83b8a6f242ea ("drm/gem: Fix mmap fake offset handling for drm_gem_object_funcs.mmap")
