[PATCH 3/3] arm64: dts: rockchip: Add ArmSoM Sige7s board

[Jianfeng Liu <liujianfeng1994@gmail.com>]

The ArmSoM Sige7s shares its hardware design with the CoolPi 4B.

Add a board DTS that includes the shared CoolPi 4B description and
provides the ArmSoM model and board compatible. Retain coolpi,pi-4b
as a fallback compatible and register the new DTB in the Makefile.
