ASoC: Move card list initialization to snd_soc_register_card

All ASoC cards need snd_soc_initialize_card_lists called. Previously, it was
only called for cards backed by a "soc-audio" platform device, via
soc_probe(). However, it's also needed for cards backed by other platform
devices, and registered directly via snd_soc_register_card().
