drivers/sof: Add new driver to generate ACPI _DSD table

Add a new chip driver for boards which use SOF (Sound Open Firmware)
OS drivers, which will be attached to the HDAS device and generate
entries in an ACPI _DSD table for the OS driver to use. This will allow
the OS drivers to easily determine the correct topology for the speaker
and jack amplifiers and correct microphone configuration.

TEST=tested with rest of patch train
