[PATCH] 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-20170217-v4.10-rc8' tag of Simon
Horman's 'renesas.git' repo.

The IMR-LX4 binding was documented in the IMR driver patch; I don't expect it
to  change  even if the driver  would be  rewritten  for DRM...
