arm64: dts: qcom: Add SDM632 device tree

Snapdragon 632 is based on msm8953 with some minor differences, mostly
in the CPUs.

SDM632 is using Kryo 250 instead of ARM Cortex A53 and has some
differences in the thermal zones, mainly there being only one thermal
zones for the first 4 cores (efficiency cores) but keeps one thermal
zone per core for the remaining 4 cores (performance cores).
