[SRU][Eoan][PATCH 1/3] ASoC: SOF: Intel: hda: use fallback for firmware name

[Hui Wang]

From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>

BugLink: https://bugs.launchpad.net/bugs/1857409

We have platforms such as CFL with no known I2S codec being used, and
the ACPI tables are currently empty, so fall-back to using the
firmware filename used in nocodec mode
