[PATCH v2] arm64: dts: r8a7795: add IMR-LX4 support

[sergei.shtylyov@cogentembedded.com (Sergei Shtylyov)]

Describe the IMR-LX4 devices in the R8A7795 device tree.

Based on the original (and large) patch by Konstantin Kozhevnikov
<Konstantin.Kozhevnikov@cogentembedded.com>.

Signed-off-by: Konstantin Kozhevnikov <Konstantin.Kozhevnikov@cogentembedded.com>

Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>

---
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;
- added Geert's tag.
