Subject: [PATCH] ASoC: rsnd: ssiu: clear SSI_MODE for non TDM Extended modes
Git-commit: a91d7fb97092d6b840af5899ded3b389603fd7f1
Patch-mainline: v4.15-rc6
References: bsc#1051510

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")
