Subject: [PATCH v4 08/24] ASoC: renesas: rz-ssi: Remove the rz_ssi_get_dai() function

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Remove the rz_ssi_get_dai() function and use directly the
snd_soc_rtd_to_cpu() where needed or the struct device pointer embedded
in the struct rz_ssi_priv objects.
