[UPSTREAM v6.5]: arm64: tegra: Enable thermal support on Jetson Orin NX

Browse Source 
Enable the TJ thermal zone and hook up cooling maps for the PWM-
controlled fan and two trip points.

This also removes a duplicate definition of the PWM fan and changes its
cooling levels. This should have no effect, though, because the fan
wasn't previously connected to anything and by default would be turned
off at probe time.
