[PATCH 1/5] ASoC: mediatek: mt8195-mt6359: Properly register sound card for SOF

[AngeloGioacchino Del Regno]

Adding a probe callback on this snd_soc_card is required when
Sound Open Firmware support is desired, as we need to appropriately
populate the stream_name for SOF to be able to bind widgets.
Failing to do so will produce errors when applying the SOF topology
leading to card registration failure (so, no sound).
While at it, also make sure to fill the topology_shortname as required.
