[U-Boot] [PATCH v2 3/3] arm: dts: Add MMC nodes for HiKey board

[Manivannan Sadhasivam]

From: Manivannan Sadhasivam <manivannan.sadhasivam at linaro.org>

Add MMC nodes for HiKey board based on HI6220 SoC. There are three MMC
controllers in this SoC, first one used for eMMC, second one used
for SD card and third one is not used by u-boot.
