[PATCH 6/8] arm64: dts: qcom: kaanapali: Add GPU cooling

[Akhil P Oommen <akhilpo@oss.qualcomm.com>]

From: Gaurav Kohli <gaurav.kohli@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 reaching 105°C.
