From: Jiada Wang <jiada_wang@xxxxxxxxxx>
register SSI_MODE is set when SSI works in TDM Extended or
TDM (Ex-)Split mode, but it isn't reset after SSI stops.
this will cause issue, if SSI starts to work in other modes
which requie SSI_MODE to have different value.
This patch resets SSI_MODE register in .stop callback,
when last stream calls .stop.
Fixes: 186fadc132f0 ("ASoC: rsnd: add TDM Extend Mode support")
