The BreadBee and the BreadBee Crust are the same PCB with a different SoC mounted. There are two top level dts to handle this. To avoid deduplicating the parts that are more related to the PCB than the SoC (i.e. the voltage regs and LEDs) add a common dtsi that can be included in both top level dts.
