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.
