[PATCH 2/3] ARM: dts: sun8i: add pinmux for V3s mmc1

[Icenowy Zheng]

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.
