[PATCH] Revert "mmc: sdhci-s3c: Add clk_(enable/disable) in runtime suspend/resume"

["Heiko Stübner" <heiko@sntech.de>]

This reverts commit 2abeb5c5ded2e7f7d288058426fb0ae852adc77f, as it breaks
machines using the gpio-based card-detect option with a loop of

        mmc0: Timeout waiting for hardware interrupt.
        mmc0: Internal clock never stabilised.
        mmc0: Timeout waiting for hardware interrupt.
