[PATCH] arm64: dts: qcom: x1e80100: Add '#cooling-cells' for CPU nodes

[Manivannan Sadhasivam <mani@kernel.org>]

From: Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>

Enable passive cooling for CPUs in the X1E80100 SoC by adding the
'#cooling-cells' property. This will allow the OS to mitigate the CPU
power dissipation with the help of SCMI DVFS.
