Olimex Teres-I is a laptop DIY kit, and A64-Teres-I is its mainboard. https://linux-sunxi.org/Olimex_Teres-A64

This patch enables support for the A64-Teres-I board to u-boot, including enabling screen backlight (lacking from Linux device-tree).

sun50i-a64-teres-i.dts is copied verbatim from Linux 5.0. Cosmetic warnings regarding whitespace and placement of SPDX notice for this file was ignored.

config and .dtsi file are adapted from pinebook files.
