* All tables must be byte-packed to match the ACPI specification, since
NHLT (Non-HDAudio Link Table) provides configuration of audio endpoints for Intel SST (Smart Sound Technology) DSP products. Similarly to other ACPI tables, data provided by BIOS may not describe it correctly, thus overriding is required. ACPI override mechanism checks for unknown signature before proceeding. Update known signatures array to support NHLT. CC: Erik Kaneda <erik.kaneda@intel.com> CC: Robert Moore <robert.moore@intel.com> CC: Rafael J.
