[PATCH 1/5] ASoC: simple-card: remove unused variable from simple_parse_of()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

commit d9ffff696c5b4 ("ASoC: simple-card: Use snd_soc_of_parse_aux_devs()")
switched to use snd_soc_of_parse_aux_devs() on simple_parse_of().
Thus noone is using *top anymore. Let's cleanup unused variable.
