[PATCH v5 08/10] ACPI / scan: Create platform device for CLSA0100 and CSC3551 ACPI nodes

The ACPI device with CLSA0100 or CSC3551 is a sound card
with multiple instances of CS35L41 connectec by I2C to
the main CPU.

We add an ID to the i2c_multi_instantiate_ids list to enumerate
all I2C slaves correctly.
