arm64: tegra: Device tree changes for v6.15-rc1

Browse Source 
This contains a patch to remove an unusable key that was erroneously
 exposed as well as a fix to support GPUs with a large amount of video
 memory on IGX Orin.
 
 Finally, some additional devices, such as a temperature sensor, are
 enabled on Jetson TX1, the output voltage of some pins is adjusted and
 the VDD_LCD_1V8_DIS power supply now uses the correct enable GPIO.
