ASoC: ACPI: add new fields for SOF support

Browse Source 
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
