ASoC: sh: fsi: add fsi_version() and removed meaningless version check
This patch adds fsi_version() function for accessing version. And there were some meaningless version check which never hit. This patch removed it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
