[PATCH] ASoC: sunxi: sun4i-codec: fill ASoC card owner

[bage at linutronix.de]

From: Bastian Germann <bage at linutronix.de>

card->owner is a required property and since commit 81033c6b584b ("ALSA:
core: Warn on empty module") a warning is issued if it is empty. Add it.
This fixes following warning observed on Lamobo R1:
