This could just be
fn debugfs_init(dir: &debugfs::ScopeRef<'_, Self::RegistrationData<'_>>)
as it is only needed to populate files / directories for exposing things in
RegistrationData.
Subsequent debugfs::Scopes can be registered from drm::File<'_>::open() and
IOCTLs (I also work on introducing HRT private data for IOCTLs; semantically
equivalent to a Vec in DriverFile<'_> or RegistrationData<'_>, but managed by
the subsystem).
