It seems like you ought to include cap-mmc-highspeed in addition to
cap-sd-highspeed, but I could be wrong.  I know that I have some
full-sized MMC cards (not eMMC) that can be plugged into an SD card
slot.  I know that the SD/MMC slot on this port only has 4 pins on
exynos5250, but I think you can still run MMC highspeed on 4 pins,
right?
