[ 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.
