[PATCH v2 6/7] arm64: dts: nuvoton: npcm845-evb: Import optee node from u-boot device tree

[Mathieu Dubois-Briand]

U-Boot is defining its own device tree for this platform. Among all
differences, a firmware node to enable communication with OP-TEE is
added. Importing this node here will reduce these differences.
