[PATCH 1/3] ARM: dts: exynos: Document eMMC/SD/SDIO devices in Exynos5250 Snow board

[Javier Martinez Canillas <javier@osg.samsung.com>]

There's a cognitive load to figure out which mmc device node corresponds
to the eMMC flash, uSD card and WiFI SDIO module on the Snow boards.

So it's better to have comments in the DTS to make this more clear.
