[PATCH 6/6] arm64: dts: allwinner: a64: enable ANX6345 bridge on Teres-I

[Torsten Duwe]

From: Icenowy Zheng <icenowy@xxxxxxx>

Teres-I has an anx6345 bridge connected to the RGB666 LCD output, and
the I2C controlling signals are connected to I2C0 bus. eDP output goes
to an Innolux N116BGE panel.

Enable it in the device tree.
