[PATCH v2] arm64: dts: r8a7796: add IMR-LX4 support

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

Describe the IMR-LX4 devices in the R8A7796 device tree.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

---
This patch is against the 'renesas-devel-20170626-v4.12-rc7' tag of Simon
Horman's 'renesas.git' repo.

The IMR-LX4 bindings were documented in the IMR driver patch and ACK'ed by Rob
Herring, so I don't expect them to change...

Changes in version 2:
- added SoC specific "compatible" prop values;
- refreshed the patch.
