ASoC: ak4613: cares Simple-Audio-Card case for TDM 

Renesas is the only user of ak4613 on upstream for now, and
commit f28dbaa958 ("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.
