thermal: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

thermal/hwmon: Use the right device for devm_thermal_add_hwmon_sysfs()

The devres variant of thermal_add_hwmon_sysfs() only takes the thermal
zone structure pointer as parameter.

Actually, it uses the tz->device to add it in the devres list.

It is preferable to use the device registering the thermal zone
instead of the thermal zone device itself. That prevents the driver
accessing the thermal zone structure internals and it is from my POV
more correct regarding how devm_ is used.

thermal/core: Use the thermal zone 'devdata' accessor in thermal located drivers

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.

In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.

Use the devdata accessor introduced in the previous patch.

No functional changes intended.

thermal: Remove core header inclusion from drivers

As the name states "thermal_core.h" is the header file for the core
components of the thermal framework.

Too many drivers are including it. Hopefully the recent cleanups
helped to self encapsulate the code a bit more and prevented the
drivers to need this header.

Remove this inclusion in every place where it is possible.

Some other drivers did a confusion with the core header and the one
exported in linux/thermal.h. They include the former instead of the
latter. The changes also fix this.

The tegra/soctherm driver still remains as it uses an internal
function which need to be replaced.

The Intel HFI driver uses the netlink internal framework core and
should be changed to prevent to deal with the internals.

No functional changes intended.

thermal/drivers/qcom: Fix lock inversion

The thermal-zone-device lock is held by core when setting trip points
and the driver takes its chip lock in the corresponding callback.

Fetching the thermal trip points using thermal_zone_get_trip() also
involves taking the thermal-zone-device lock, which means that the chip
lock can not be held when doing so.

Drop the chip lock temporarily during probe to avoid the lock inversion
that was detected by lockdep:
