The thermal monitor is used to monitor arbitrary ADC-based thermal
sensors. It is suitable for use in thermal zones. Add support for it in
PM660.

Can we enable it by default?

This is for the ADC thermal monitor, and not the ADC itself. I don't see
the need to allocate channels just so this can be enabled by default,
since the thermal monitor's purpose is mostly to send interrupts when
the ADC values go above or below a certain threshold.
