Add the card-detect and write-protect GPIO pins for OdroidXU3/XU4
SD card by adding pinctrl setting for wp-gpio pin and set it to
active low.
This also removes debug messages:
dwmmc_exynos 12220000.mmc: No GPIO consumer cd found
dwmmc_exynos 12220000.mmc: No GPIO consumer wp found

Fix the commit message and squash it with cd-gpios and wp-gpio
patches into single patch as suggested by Krzysztof.
