Alexey Kardashevskiy fb952a7683 powerpc/ioda/iommu/debugfs: Generate unique debugfs entries
[ Upstream commit d73b46c3c1449bf27f793b9d9ee86ed70c7a7163 ]

The iommu_table::it_index is a LIOBN which is not initialized on PowerNV
as it is not used except IOMMU debugfs where it is used for a node name.

This initializes it_index witn a unique number to avoid warnings and
have a node for every iommu_table.

This should not cause any behavioral change without CONFIG_IOMMU_DEBUGFS.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
