[PATCH 2/2] arm64: dts: qcom: shikra: Enable CDSP & Modem cooling

[Dipa Ramesh Mantre]

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

Set up CDSP/Modem cooling by throttling the CDSP and modem when they
reach 115°C using the QMI TMD cooling device framework.
