ASoC: Intel: add codec name prefix to ACPI machine description
The current SOF machine driver adds a name prefix for each codec, mainly to differentiate ALSA controls for left and right amplifiers. This is a good idea, but the machine driver duplicates some of the information that already exists in ACPI descriptors, so add those prefixes there. Follow-up patches will make use of the information encoded in these tables and remove duplication.
