[PATCH v2 8/9] arm64: dts: qcom: eliza: Add GPU cooling

[Akhil P Oommen]

From: Gaurav Kohli <gaurav.kohli at oss.qualcomm.com>

Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures. Set up GPU cooling by throttling the GPU speed
when it reaches 95°C.
