arm64: allwinner: a64: enable ANX6345 bridge on Pinebook

Pinebook has an ANX6345 bridge connected to the RGB666 LCD output, and
the I2C controlling signals are connected to R_I2C bus.

Enable it in the device tree, and add a usable EDID from the panel's
datasheet (at least 14" Pinebook used a panel without EDID).
