[PATCH 1/2] arm64: dts: renesas: initial V3MSK board device tree

[Sergei Shtylyov]

Add the initial device  tree for the V3M Starter Kit board.
The board has 1 debug serial port (SCIF0); include support for it,
so that the serial console can work.

Based on the original (and large) patch by Vladimir Barinov.
