ASoC: imx-card: Set card.owner to avoid a warning calltrace if SND=m
[ Upstream commit 47d7d3fd72afc7dcd548806291793ee6f3848215 ]
In most Linux distribution kernels, the SND is set to m, in such a
case, when booting the kernel on i.MX8MP EVK board, there is a
warning calltrace like below:
Call trace:
snd_card_init+0x484/0x4cc [snd]
snd_card_new+0x70/0xa8 [snd]
snd_soc_bind_card+0x310/0xbd0 [snd_soc_core]
snd_soc_register_card+0xf0/0x108 [snd_soc_core]
devm_snd_soc_register_card+0x4c/0xa4 [snd_soc_core]
That is because the card.owner is not set, a warning calltrace is
raised in the snd_card_init() due to it.
