ARM: dts: exynos: correct TMU phandle in Odroid XU

TMU node uses 0 as thermal-sensor-cells, thus thermal zone referencing
it must not have an argument to phandle.  Since thermal-sensors property
is already defined in included exynosi5410.dtsi, drop it from
exynos5410-odroidxu.dts to fix the error and remoev redundancy.
