Currently the dmic_nrfx_pdm read implementation treats a timeout as an
error, in that a logging error message is produced when no PDM data is
available. However, for non-(or minimally-)blocking applications this is
normal behavior. Classified this way, the logger is flooded with error
messages unnecessarily, unless the log level is changed for the dmic
module, which is not desirable.
This modification simply changes the log-level to debug so the
application user can then decide whether or not a failed read needs to
produce an error message.
