Merge series "ASoC: SOF: Intel: fix to dsp state dump trace levels" from Kai Vehmanen <kai.vehmanen@linux.intel.com>: 

Small series that addresses a problem where DSP status dump
for a failure case, ends up being printed as as debug print. This
is important information for any bug report. While at it, the series
contains a few cleanups to related code.

Ranjani Sridharan (3):
  ASoC: SOF: Intel: hda: remove duplicated status dump
  ASoC: SOF: modify the SOF_DBG flags
  ASoC: SOF: Intel: hda: fix the condition passed to sof_dev_dbg_or_err
