This patchset is to support eMMC reset using DT for some exynos boards e.g. Odroid X2/U3/XU3.

It needs to reset eMMC memory to perform complete reboot, so we should handle nRESET_OUT line specially. nRESET_OUT line is connected to gpio and it can have different gpio by boards, so we will get gpio from DT.

This patchset is based on http://git.denx.de/u-boot-dm.git gpio-working branch.

Thanks.

Changes from v1:

• s/SD4_nRESET_OUT/nRESET_OUT
• Remove codes for non DT case
• Add comments about eMMC reset delay time
