Subject: [PATCH 2/3] ARM: dts: exynos: Document eMMC/SD/SDIO devices in Exynos5420 Pit board

There's a cognitive load to figure out which mmc device nodes corresponds
to the eMMC flash, uSD card and WiFI SDIO module on the Peach Pit board.

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