Subject: [PATCH] ARM: dts: exynos: remove the cd-gpios property for eMMC of
 odroid-xu3/4

Odroid-xu3/4 didn't need to use the cd-gpios for detecting card.
Because Host controller has the CDETECT register through SDx_CDN line.
Host controller can know whether card is inserted or not with this
register.

When i have checked the Odroid-xu3/4, they are using CDETECT register.
(Not using exteranl cd-gpio.)

Fixes: fb1aeedb61ad ("ARM: dts: add mmc detect gpio for exynos5422-odroidxu3")
