[PATCH] ASoC: fix build warning in soc-core.c

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix kernel-doc build error. A symbol that ends with an underscore
character ('_') has special meaning in reST (reStructuredText), so add
a '*' to prevent this error and to indicate that there are several of
these values to choose from.

../sound/soc/soc-core.c:2799: ERROR: Unknown target name: "snd_soc_daifmt".
