Additionally, this will allow us to support different TPM interfaces with the same AML logic. Finally, this matches up with the TPM TIS ISA implementation. Ideally, we would be able to call `qbus_build_aml` and avoid any TPM specific code in the ACPI table generation. However, currently we still have to call `build_tpm2` anyways and it does not look like most other ACPI devices support the `ACPI_DEV_AML_IF` interface.
