In that case, please drop the @0 from the node name. We shouldn't be adding them anyway, since it causes warnings from the device tree compiler.

Allwinner V3s SoC features 3 MMC controllers, mmc0 is used as the MicroSD slot on Lichee Pi Zero, and on Lichee Pi Zero's dock mmc1 is also soldered as a MicroSD slot. Add the pinmux for mmc1, thus we can enable the MicroSD slot on the Lichee Pi Zero dock.
