Subject: [PATCH 03/03] ARM: shmobile: lager-reference: IOMMUSY1 and USB tests

From: Magnus Damm <damm+renesas@opensource.se>

Add some prototype code to allow testing of IPMMUSY1
and USB 2.0 Host controllers on the r8a7790 Lager board.

The USB 2.0 Host controllers are described via DT while
the IPMMU device is handled as platform device for now.

Not for upstream merge.
