The Processor Service Interface (PSI) model has a chip_type class level attribute, which is used to generate the content of the "compatible" DT property according to the CPU type. Since the PSI model already has specialized classes for each supported CPU type, it seems cleaner to achieve this with QOM. Provide the content of the "compatible" property with a new class level attribute.
