Subject: ASoC: rcar: avoid SSI_MODEx settings for SSI8

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


[ Upstream commit 4b30eebfc35c67771b5f58d9274d3e321b72d7a8 ]

SSI8 is is sharing pin with SSI7, and nothing to do for SSI_MODEx.
It is special pin and it needs special settings whole system,
but we can't confirm it, because we never have SSI8 available board.

This patch fixup SSI_MODEx settings error for SSI8 on connection test,
but should be confirmed behavior on real board in the future.
