ACPI: scan: Create platform device for CS35L56
commit 1cd0302be5645420f73090aee26fa787287e1096 upstream.
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.
