I'm not convinced about "facebook,common-bmc" as a compatible. Is there
actually a reason to specify anything here other than "aspeed,ast2600"?

Alternatively, perhaps list all the relevant platforms, like the p10bmc
dts?

```
$ git grep aspeed,ast2600 arch/arm/dts/ast2600-p10bmc.dts
arch/arm/dts/ast2600-p10bmc.dts:        compatible = "ibm,everest-bmc", "ibm,rainier-bmc", "ibm,p10bmc", "aspeed,ast2600";
```
