Stephan Gerhold cd9d354bdd arm64: dts: qcom: x1e80100: Add GPU cooling 
[ Upstream commit 5ba21fa11f ]

Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures. With certain high GPU loads it is possible to
reach the critical hardware shutdown temperature of 120°C, endangering the
hardware and making it impossible to run certain applications.

Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed
when reaching 95°C and polling every 200ms.
