[PATCH v7 7/9] arm64: dts: qcom: talos: Enable CDSP cooling

Unlike the CPU, the CDSP does not throttle its speed automatically
when it reaches high temperatures in talos.

Set up CDSP cooling by throttling the cdsp, when it reaches 105°C.

Add polling-delay-passive so the governor periodically evaluates
the zone during passive cooling and steps up cooling levels when
temperature stabilizes below the next trip.
