This can be changed to carrier board in next version。

>s/CM5/GenM5/

In fact, the SOM  is called  CM5 always[0]， even this laptop was called cm5 laptop from the
very beginning of the design。
They just gave it a new name GenBook when it comes to crowdsupply.

The dtsi for CM5 is aready landing upstream，I inclulde it in the current genbook dts。
