Subject: [PATCH v2 2/2] arm64: dts: uDPU: correct temperature sensors

uDPU has a pair of NCT375 temperature sensors, which are TMP75C compatible
as far as the driver is concerned.

The current LM75 compatible worked as all of the LM75 compatible sensors
are backwards compatible with the original part, but it meant that lower
resolution and incorrect sample rate was being used.

The "lm75" compatible has been deprecated anyway and is meant as fallback
in order to keep older DTS-es working.
