To extend the same idea to other devices, add TYPE_ACPI_DEV_AML_IF Interface that will provide a more generic callback which will be used not only for ISA but other devices. It will allow get rid of some data-mining and ad-hoc AML building, by asking device(s) to generate its own AML blob like it's done for ISA devices.
