ASoC: rsnd: ssiu: clear SSI_MODE for non TDM Extended modes
register SSI_MODE is set when SSI works in TDM Extended,
but it isn't reset when SSI starts to work in other modes,
thus causes issues.
This patch clearss SSI_MODE register when SSI works in modes
other than TDM Extended.
Fixes: 186fadc132f0 ("ASoC: rsnd: add TDM Extend Mode support")
