The most important thing this patch does is to add the thermal zones,
this should be reflected in the subject.
Not strictly necessary, but I'd suggest a separate patch to add the
TSENS nodes and then one for the thermal zones.

not super-important, but is a hysteresis actually needed for a critical
trip point? The system is supposed to shut down when the critical trip
point is reached, so I'd expect that the hysteresis doesn't do anything.

Also not super-important, but I wonder what the order of the thermal
zones should be. Currently this seems to be a mix of 'most important
first', group certain things and order by sensor ID.
My initial suggestion would be to use alphabetical order, though that
would put a few 'less important' zones before the CPUs. An possible
alternative could be 'CPUs first' followed by alphabetical order.
In any case, it's not really important, just wondered if there should
be a specific ordering.
If you keep more or less the current order then it seems the aoss0
and aoss1 should be grouped together.
