ASoC: ak4613: cares Simple-Audio-Card case for TDM
Renesas is the only user of ak4613 on upstream for now, and commit f28dbaa958fbd8 ("ASoC: ak4613: add TDM256 support") added TDM256 support. Renesas tested part of it, because of board connection. It was assuming ak4613 is probed via Audio-Graph-Card, but it might be probed via Simple-Audio-Card either. It will indicates WARNING in such case. This patch fixup it.
