ARM: dts: msm: move BCL cooling dev configs into sdm450 platform devicetree

The pmic device tree files will be used by multiple platforms with
different core configuration. If BCL cpu cooling devices is configured
on this pmic devicetree, it leads to compilation issue for platform
which shares the same pmic with lesser cores.

Move BCL thermal zone related cooling device configs into sdm450
platform devicetree.
