Subject: [PATCH v6 6/6] arm64: dts: qcom: Indicate rpmhpd hosts a power domain that can be used as a warming device.

RPMh hosts mx power domain that can be used to warm up the SoC.  Indicate
this by using #cooling-cells property.

v3->v4:
	- Removed subnode to indicate that mx power domain is a warming
	  device. Instead #cooling-cells is used as a power domain
	  provider property to indicate if the provider hosts a power
	  domain that can be used as a warming device.
