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.

My ocd would rather see the boolean property at the end

anyway
