This series adds DT nodes for IPMMU instances on r8a77995 together with
connections to the r8a77995 on-chip device Ethernet-AVB.

With these patches applied a white list enabled IPMMU driver may be used
to check silicon revision and then enable IPMMU in the known working cases.

The recommended IPMMU driver patch is iommu/next with the following applied:
 [PATCH v5 00/09] iommu/ipmmu-vmsa: r8a7795 support V5
 [PATCH v4 0/3] iommu/ipmmu-vmsa: r8a7796 support V4
 [PATCH 0/2] iommu/ipmmu-vmsa: r8a779(70|95) support

A patch to enable IPMMU devices is not included in this series
as Ethernet-AVB, the only device to which IPMMU is hooked up to,
is disabled.

The DT binding for r8a77995 has been submitted (as part of the
r8a779(70|95) series noted above) in conjunction with this patchset.

This is based on work by Magnus Damm.

Based on renesas-devel-20171101-v4.14-rc7
