[0/4] thermal: stm32: driver improvements

Message

The goal of this patchset is to improve stm32 thermal driver:
* add support for multiple trip points. Currently the driver supports only
2 trip points.
* rework interrupt management to avoid receiving hundreds of
interrupts when the temperature is close to a low threshold.
* fix a mistake regarding the role of an engineering value.
* suppress passive trip point on stm32mp157c because it is useless.

Pascal Paillet (4):
  thermal: stm32: implement set_trips callback
  thermal: stm32: fix IRQ flood on low threshold
  thermal: stm32: fix engineering calibration value
  ARM: dts: stm32: remove thermal passive trip point on stm32mp157c
