Use a device property "cirrus,firmware-uid" to get the unique firmware
identifier instead of using ACPI _SUB. There aren't any products that use
_SUB.
There will not usually be a _SUB in Soundwire nodes. The ACPI can use a
_DSD section for custom properties.
There is also a need to support instantiating this driver using software
nodes. This is for systems where the CS35L56 is a back-end device and the
ACPI refers only to the front-end audio device - there will not be any ACPI
references to CS35L56.
