With IPC4, the tplg files can contain platform specific configuration objects (like NHLT blobs). In practise, all Intel tplg files that have DAIs for DMIC or SSP, will have such blobcs. E.g. topology file like "sof-hda-generic-2ch.tplg" is no longer platform agnostic, so for platforms newer than Intel MTL, we need to ship multiple versions of the these topologies, and provide a unique naming so that kernel can look up the correct topology file.

Additionally, we must maintain backward compatibility for platforms already shipping (e.g. for IPC4, this means Intel MTL platforms that are included in SOF2.8 release).

Describe the solution you'd like
Add a platform prefix to all topologies that have platform dependent configuration objects. Keep old naming for platforms like Intel MTL that are already shipping.

Describe alternatives you've considered
Using different directories and duplicating all tplgs. This adds overhead to release process if we need to duplicate all topologies (even when they are in fact the same).

Additional context
Related to SOF2.8 release process lessons learnt, kernel PR thesofproject/linux#4382 and discussion about better system to package the SOF topology files for sof-bin distribution.
