[PATCH v2 6/6] arm64: allwinner: a64: enable LCD-related hardware for Pinebook

From: Icenowy Zheng icenowy@aosc.io

Pinebook has an ANX6345 bridge connected to the RGB666 LCD output and eDP panel input. The bridge is controlled via I2C that's connected to R_I2C bus.

Enable all this hardware in device tree.
