ARM: dts: qcom: ipq8064: drop invalid GCC thermal-sensor unit-address

GCC comes with syscon compatible so the thermal-sensor child node should
not have unit-address (bindings also do not expect it):

  Warning (unit_address_vs_reg): /soc/clock-controller@900000/thermal-sensor@900000: node has a unit name, but no reg or ranges property
