asoc: set card state to online after snd card registration

Browse Source 
AGM might get initialized before sound card is populated
with all pcm nodes. This will lead to AGM parsing fewer
nodes and forms incomplete list of backends.

To avoid this, kernel module sets card status to ONLINE,
and AGM waits till the card status is ONLINE before parsing
for the pcm nodes.
