Subject: [Patch v5 5/6] arm64: dts: qcom: sdm845: Remove cpufreq cooling devices for CPU thermal zones

Now that Limits h/w is enabled to monitor thermal events around cpus and
throttle the cpu frequencies, remove cpufreq cooling device for the CPU
thermal zones which does software throttling of cpu frequencies.

Reviewed-by: Bjorn Andersson <bjorn.andersson@...aro.org>
Signed-off-by: Thara Gopinath <thara.gopinath@...aro.org>
---

v2->v3:
	- Improved the subject header and descrption to better reflect the
	  patch as per Matthias's review comments.

v1->v2:
	Removing only cooling maps for cpu specific thermal zones keeping the
	trip point definitions intact as per Daniel's suggestion. This is to
	ensure that thermal zone temparature and trip violation information is
	available to any userspace daemon monitoring these zones.
