The ACPI IDs used in the CS35L56 HDA drivers are all handled by the serial multi-instantiate driver which starts multiple Linux device instances from a single ACPI Device() node.
As serial multi-instantiate is not an optional part of the system add it as a dependency in Kconfig so that it is not overlooked.
