[01/11] ASoC: simple-card-utils: remove both playback/capture_only check

Commit Message

soc-pcm.c :: soc_get_playback_capture() will indicate error
if both playback_only / capture_only were true.

Thus, graph_util_parse_link_direction() which setup playback_only /
capture_only don't need to check it.
And, its return value is not used on existing driver. Let's remove it.
