From: Mateusz Gorski <mateusz.gorski@xxxxxxxxxxxxxxx> commit 1b290ef023b3eeb4f4688b582fecb773915ef937 upstream. Add alternative topology binary file name based on used machine driver and fallback to use this name after failed attempt to load topology file with name based on NHLT. This change addresses multiple issues with current mechanism, for example - there are devices without NHLT table, and that currently results in tplg_name being empty.
