Javier Martinez Canillas 4cf9863485 ARM: dts: exynos: Document eMMC/SD/SDIO devices in Snow and Peach boards 
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, Peach Pi
and Pit boards.

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