[PATCH] arm64: dts: r8a77965-salvator-xs: Add support for Salvator-XS with R-Car M3-N

[Geert Uytterhoeven]

From: Takeshi Kihara <takeshi.kihara.df at renesas.com>

Add initial support for the Renesas Salvator-XS (Salvator-X 2nd version)
development board equipped with an R-Car M3-N SiP.

Most features are enabled through the shared salvator-xs.dtsi board
description.  The memory configuration is specific to the M3-N SiP.
