ASoC: bcm: add missing .owner fields in sound card drivers

If snd_soc_card.owner is not set the kernel won't do usage refcounting
and one can remove the card driver module while it's in use (eg playback
active) - which leads to a kernel crash.

The missing owner field also prevents ALSA slot ordering
(options snd slots=module-name1,module-name-2,...) from working with
the I2S cards as it has no module name to match against.

Fix these issues by setting the .owner field in the snd_soc_card structs.
