ASoC: rsnd: add missing TDM Split mode support for simple-card
commitf69f452243
("ASoC: rsnd: add TDM Split mode support") added TDM Split mode support for rsnd driver. But, it cares audio-graph-card style only. We can't use TDM Split mode on simple-card style now. This patch fixup this issue. Fixes:f69f452243
