Subject: [PATCH 12/12] arm64: dts: renesas: Add initial device tree for RZ/G3L SMARC EVK board

From: Biju Das <biju.das.jz@...renesas.com>

Add the initial device tree for the Renesas RZ/G3L SMARC EVK board.

Added placeholders to avoid compilation error with the common code in
renesas-smarc2.dtsi.
