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.
