[PATCH RESEND v2 12/12] arm64: allwinner: a64: enable LCD-related hardware for TERES-I

[Vasily Khoruzhick <anarsoul-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Icenowy Zheng <icenowy-h8G6r0blFSE@public.gmane.org>

TERES-I has an ANX6345 bridge connected to the RGB666 LCD output and
eDP panel input. The bridge is controlled via I2C that's connected to
I2C0 bus.

Enable all this hardware in device tree.
