ASoC: SOF: Intel: hda-stream: Always use at least two BDLE for transfers
The HDA specification states that the SDnLVI (Last Valid Index) must be at
least 1 (two BDLE entry).
Update the debug prints as well to provide better information.
While the LVI=0 worked so far without issues, it is better to align with
the specification to avoid unforeseen issues with FW loading.
Notes:
- The LVI > 0 rules is valid and honored for audio use cases
- LVI == 0 is used with software controlled (SPIB) transfers only for
firmware and library loading, which is permitted by the hardware
- This is not spelled out in the specification and it is better to avoid
cases
