[PATCH v3 11/11] arm64: allwinner: a64: enable LCD-related hardware for Pinebook

[Vasily Khoruzhick via dri-devel]

From: Icenowy Zheng <icen...@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.

There're pinebooks with 3 different panels in the wild, all 3 with
different timings. Add all the compatibles to panel node and hope that
we can get correct timings from EDID. If reading EDID fails it's up to
firmware to fixup compatible string.

Enable all this hardware in device tree.
