[PATCH v6 3/5] arm64: dts: rockchip: add cooling map and trip points for gpu to rk356x

[Michael Riesch <michael.riesch@wolfvision.net>]

From: Alex Bee <knaerzche@gmail.com>

RK356x SoCs have a second thermal sensor for the GPU. This adds the
cooling map and trip points for it to make use of its contribution as
a cooling device.
