Subject: [PATCH 1/4] arm64: dts: qcom: x1e80100: Fix video thermal zone

A passive trip point at 125°C is pretty high, this is usually the
temperature for the critical shutdown trip point. Also, we don't have any
passive cooling devices attached to the video thermal zone.

Change this to be a critical trip point, and add a "hot" trip point at
90°C for consistency with the other thermal zones.
