[alsa-devel] [RFC PATCH 3/8] ASoC: ACPI: add new fields for SOF support

[Pierre-Louis Bossart]

To prepare for SOF integration, we need new fields in the machine table.
It is intended that the same table is used for both closed-source and
open-source firmware to avoid repeating ACPI-related information
multiple times
No functional change
