From: Sathyanarayana Nujella <sathyanarayana.nujella@xxxxxxxxx> [ Upstream commit 5253a73d567dcd75e62834ff5f502ea9470e5722 ] Add topology filename override based on system DMI data matching, typically to account for a different hardware layout. In ACPI based systems, the tplg_filename is pre-defined in an ACPI machine table. When a DMI quirk is detected, the sof_pdata->tplg_filename is not set with the hard-coded ACPI value, and instead is set with the DMI-specific filename.
