ASoC: sh: rz-ssi: Add rz_ssi_set_substream() helper function
A copy of substream pointer is stored in priv structure during
rz_ssi_dai_trigger() callback ie in SNDRV_PCM_TRIGGER_START case
and the pointer is assigned to NULL in case of SNDRV_PCM_TRIGGER_STOP.

The driver used the locks only in rz_ssi_stream_is_valid() and assigned
the local substream pointer to NULL in rz_ssi_dai_trigger() callback but
never locked it while making a local copy.

This patch adds the rz_ssi_set_substream() helper function to set the
substream pointer with locks acquired and replaces the instances of
setting the local substream pointer with the rz_ssi_set_substream()
function.
