Configure the thermals for the XO_THERM thermistor connected to the
PMK8003 (which is called PMK8350 in software).

The ADC configuration for PMK8350_ADC7_AMUX_THM1_100K_PU has already
been added in the past.

The trip points can really only be considered as placeholders, more
configuration with cooling etc. can be added later.
