arm64: dts: qcom: sm7225-fairphone-fp4: Add PM6150L thermals

Configure the thermals for the PA_THERM1, MSM_THERM, PA_THERM0,
RFC_CAM_THERM, CAM_FLASH_THERM and QUIET_THERM thermistors connected to
PM6150L.

Due to hardware constraints we can only register 4 zones with
pm6150l_adc_tm, the other 2 we can register via generic-adc-thermal.

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