ASoC: Fixes for MT8195 SOF support

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:

This series fixes Sound Open Firmware support for MT8195 by making
sure that the sound card driver is actually able to probe and IPC
can finally happen.
It is now possible to get DSP support for audio.

Tested on MT8195 Tomato - Acer Chromebook Spin 513 CP513-2H (Pipewire).
