[U-Boot] [PATCH 1/2] Exynos4412: pinmux: disable pull for MMC pins

[Przemyslaw Marczak]

There are 8 pins for SD card in Exynos, but the MUX was configured
only for 7, since the one was used for card detection.
This caused the pin's pull wrong configuration.

This commit fixes this and the card detect can work properly,
after call this function.

Tested-on: Odroid U3 and Odroid X2.
