PATCH 1/1 ARM: dts: nuvoton: Add MMC Nodes

We have the driver support code, now we just need to expose the device node which can export the SDHCI and SDMMC properties for the 2 MMC controllers in the npcm7xx. Tested on real hardware to verify that the MMC controller is functional with filesystem access.

Thanks, I've applied this to be picked up through the BMC tree.
