[PATCH 07/16] ASoC: SOF: sof-audio: preserve topology filename override in nocodec mode

[Pierre-Louis Bossart]

If the topology filename is modified at a higher level, be it with a
DMI quirk or a kernel module parameter, we don't want to use the
default 'nocodec' topology name extracted from descriptors.
