[PATCH 1/3] arm64: tegra: Add regulator for Jetson AGX Thor thermal sensor

[Jon Hunter]

Add the 1.8V regulator that supplies the thermal sensor on the Jetson
AGX Thor module to fix the following warning:

 WARNING KERN lm90 5-004c: supply vcc not found, using dummy regulator

Note that this 1.8V regulator is supplied by a 5.0V regulator that is
located on the carrier board for the Jetson AGX Thor platform.
