This adds a device tree controlled option to enable PMC-based
thermal reset in overheating situations. Thermtrip is supported on
Tegra30, Tegra114 and Tegra124. The thermal reset only works when
the thermal sensors are calibrated, so a soctherm driver is also
required.

The thermtrip event is triggered by the soctherm block, and all
soctherm sensors default to showing a temperature of zero Celsius
before they are initialized. Because of this, it is safe to initialize
thermtrip and soctherm in any order.

This looks good to me. I'm not sure if I asked before, but can this be
tested? Can we somehow trick thermtrip into reporting a temperature that
would trigger this?

Yep, you can find a program here: https://gist.github.com/cyndis/66126c9c176b5f94a76f

It sets the thermtrip threshold to zero degrees.
