[PATCH] mmc: sdhci-s3c: hide forward declaration of of_device_id behind CONFIG_OF

[Krzysztof Kozlowski]

The struct of_device_id is not defined with !CONFIG_OF so its forward
declaration should be hidden to as well.  This should address clang
compile warning:

  drivers/mmc/host/sdhci-s3c.c:464:34: warning: tentative array definition assumed to have one element
