[PATCH v6 4/4] arm64: dts: qcom: Add Acer Aspire 1

From: Nikita Travkin
Date: Sat Apr 08 2023 - 04:14:35 EST

Acer Aspire 1 is a WoA laptop based on Snapdragon 7c gen1 platform.

The laptop design is similar to trogdor in the choice of primary
components but the specifics on usage of those differ slightly.

Add the devicetree for the laptop with support for most of the
hardware present.
