ASoC: simple-card-utils: Check value of is_playback_only and is_capture_only

The audio-graph-card2 gets the value of 'playback-only' and
'capture_only' property in below sequence, if there is 'playback_only' or
'capture_only' property in port_cpu and port_codec nodes, but no these
properties in ep_cpu and ep_codec nodes, the value of playback_only and
capture_only will be flushed to zero in the end.

graph_util_parse_link_direction(lnk,            &playback_only, &capture_only);
graph_util_parse_link_direction(ports_cpu,      &playback_only, &capture_only);
graph_util_parse_link_direction(ports_codec,    &playback_only, &capture_only);
graph_util_parse_link_direction(port_cpu,       &playback_only, &capture_only);
graph_util_parse_link_direction(port_codec,     &playback_only, &capture_only);
graph_util_parse_link_direction(ep_cpu,         &playback_only, &capture_only);
graph_util_parse_link_direction(ep_codec,       &playback_only, &capture_only);

So check the value of is_playback_only and is_capture_only in
graph_util_parse_link_direction() function, if they are true, then rewrite
the values, and no need to check the np variable as
of_property_read_bool() will ignore if it was NULL.
