This is per the requirement in Documentation/acpi/enumeration.txt:

"Currently the kernel is not able to automatically determine from which ACPI
device it should make the corresponding platform device so we need to add
the ACPI device explicitly to acpi_platform_device_ids list defined in

Without adding the device here it would not be discovered and probe would not be
called during init.
