The ACPI device CSC3556 is a Cirrus Logic CS35L56 mono amplifier which is used in multiples, and can be connected either to I2C or SPI. There will be multiple instances under the same Device() node. Add it to ignore_serial_bus_ids and handle it in the serial-multi-instantiate driver. There can be a 5th I2cSerialBusV2, but this is an alias address and doesn't represent a real device. Ignore this by having a dummy 5th entry in the serial-multi-instantiate instance list with the name of a non-existent driver, on the same pattern as done for bsg2150.
