[PATCH 3/4] arm64: dts: qcom: Add Retroid Pocket 6

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

The Retroid Pocket 6 is a high-performance Android-based handheld gaming
console powered by the Qualcomm Snapdragon 8 Gen 2 processor featuring a
5.5-inch AMOLED touchscreen.

This is based on the support by ROCKNIX, however their history does not
show who the original author was, so direct attributation cannot be
given.
