ARM: dts: iwg20d-q7: Rework DT architecture
Since the same carrier board may host RZ/G1M and RZ/G1N based Systems on Module, the DT architecture for iwg20d-q7 needs better decoupling. This patch provides: * iwg20d-q7-common.dtsi - its purpose is to define the carrier board definitions, and its content is basically the same as the previous version of r8a7743-iwg20d-q7.dts, only it has no reference to the SoM .dtsi, and that's why the filename doesn't mention the SoC name any more. * r8a7743-iwg20d-q7.dts - its new purpose is to put together the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board .dtsi defined by this very patch, along with "model" and "compatible" properties. The final DT architecture to describe the board is now: r8a7743-iwg20d-q7.dts # Carrier Board + SoM ├── r8a7743-iwg20m.dtsi # SoM │ └── r8a7743.dtsi # SoC └── iwg20d-q7-common.dtsi # Carrier Board and maximizes the reuse of the definitions for the carrier board and for the SoM.
