A change made in the final version of IOMMU debugfs support replaced the
public function iommu_debugfs_new_driver_dir() by the public dentry
iommu_debugfs_dir in <linux/iommu.h>, but forgot to update both the
implementation in iommu-debugfs.c, and the patch description.
Fix this by exporting iommu_debugfs_dir, and removing the reference to
and implementation of iommu_debugfs_new_driver_dir().
Fixes: bad614b24293ae46 ("iommu: Enable debugfs exposure of IOMMU driver
internals")
