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.

Don't merge this, I've discovered that we need a 5th entry in the
table, so I will send a V3.
