ASoC: Intel: hda-sdw-bpt: return ENXIO if SOF DSP is not first booted

The BPT stream needs SOF DSP's support. We can only open a BPT stream
after the SOF DSP FW is downloaded and booted completed.
It also doesn't make sense to wait for SOF FW boot instead of starting
common read/write immediately.
