    ARM: dts: exynos: correct TMU phandle in Odroid HC1
    
    [ Upstream commit 2e3d0e20d8456f876607a8af61fdb83dfbf98cb6 ]
    
    TMU node uses 0 as thermal-sensor-cells, thus thermal zone referencing
    it must not have an argument to phandle.  This was not critical before,
    but since rework of thermal Devicetree initialization in the
    commit 3fd6d6e2b4e8 ("thermal/of: Rework the thermal device tree
    initialization"), this leads to errors registering thermal zones other
    than first one:
    
      thermal_sys: cpu0-thermal: Failed to read thermal-sensors cells: -2
      thermal_sys: Failed to find thermal zone for tmu id=0
      exynos-tmu 10064000.tmu: Failed to register sensor: -2
      exynos-tmu: probe of 10064000.tmu failed with error -2
