[PATCH v2] mmc: sdhci-s3c: fix the card detection in runtime-pm

["Heiko Stübner" <heiko@sntech.de>]

If host clock is disabled, host cannot detect a card
in case of using the internal or gpio card-detect for detection.

I've added the SDHCI_CD_GPIO to the conditional. With this change it works
on my machine. But I'm not sure if this would also be necessary for the 
external card detect.
