[PATCH v2 0/3] Add thermal management support for STi platform

This patch series enhances the st_thermal driver in order to enable
support for thermal zones. The changes include:

1. Replace deprecated PM runtime macros with their updated counterparts.
2. Implementing devm_* based thermal of zone functions within the driver.
3. Updating the stih418 device-tree.

The device-tree patch depends on an earlier patch sent to the mailing
list [1].

As it is currently implemented, an alert threshold of 85°C is set to
trigger the CPU throttling, and when the temperature exceeds the
critical threshold of 95°C, the system shuts down. There is for now no
active cooling device on the platform, which explains the use of the
cpufreq framework.
