Revert "rockchip: rk3399: enable sdhci clk for emmc"

This reverts commit 462e1413 ("rockchip: rk3399: enable sdhci clk
    for emmc")

Enabling this clock in coreboot is no longer needed as it's handled
    in the kernel driver now.

BUG=chrome-os-partner:52873
    TEST=boot from usb/sdcard and check there is /dev/mmcblk0
    BRANCH=none
