ASoC: atmel: mchp-pdmc: Skip ALSA restoration if substream runtime is uninitialized
Update the driver to prevent alsa-restore.service from failing when
reading data from /var/lib/alsa/asound.state at boot. Ensure that the
restoration of ALSA mixer configurations is skipped if substream->runtime
is NULL.
