rockchip: rk3399: enable sdhci clk for emmc

Hardware / Coreboot - Shunqian Zheng [rock-chips.com] - 18 May 2016 13:23 UTC

If booting from sdcard/usb, kernel can't recognize the /dev/mmcblk0. Before kernel find it's root cause, we add this workaround patch to enable clk for emmc.

BRANCH=none BUG=chrome-os-partner:52873 TEST=boot from sdcard and check the /dev/mmcblk0 exists
