[PATCH 3/6] ASoC: ak4613: return error if it was setup as clock provider

[Kuninori Morimoto]

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

Renesas is only user of ak4613 on upstream, and it is tested
only under "clock consumer" because of board mounting situation.

Thus, "clock provider" is not supperted/tested.
This patch return error if it was setup as clock provider.
