From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

simple-card-utils might be used as module, but MODULE_xxx()
information was missed. This patch adds it.
Otherwise, we will have below error, and can't use it.
Specil thanks to Kevin.

> insmod simple-card-utils.ko
simple_card_utils: module license 'unspecified' taints kernel.
Disabling lock debugging due to kernel taint
simple_card_utils: Unknown symbol snd_soc_of_parse_daifmt (err 0)
simple_card_utils: Unknown symbol snd_soc_of_parse_card_name (err 0)
insmod: can't insert 'simple-card-utils.ko': \
unknown symbol in module, or unknown parameter
