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.
