arm: dts: exynos: Fix card-detect polarity for SD card on Odroid U3/X2

Card detect line for SD-card on Odroid U3/X2 boards are active low, so
add cd-inverted property to indicate this, as u-boot's GPIO driver doesn't
support specifying line polarity. This restores S5P_SDHCI driver operation
on Odroid U3/X2 boards.
