ASoC: sh: fsi: remove fsi_module_init/kill
FSIA/B ports is enabled by default when power-on, and current FSI is supporting RuntimePM. In addition, current fsi_module_init/kill doesn't care simultaneous playback/recorde. This mean FSI port control is not needed. This patch remove fsi_module_init/kill Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
