[v4,00/19] Self-encapsulate the thermal zone device structure

The exported thermal headers expose the thermal core structure while those
should be private to the framework. The initial idea was the thermal sensor
drivers use the thermal zone device structure pointer to pass it around from
the ops to the thermal framework API like a handler.

Unfortunately, different drivers are using and abusing the internals of this
structure to hook the associated struct device, read the internals values, take
the lock, etc ...

In order to fix this situation, let's encapsulate the structure leaking the
more in the different drivers: the thermal_zone_device structure.

This series revisit the existing drivers using the thermal zone private
structure internals to change the access to something else. For instance, the
get_temp() ops is using the tz->dev to write a debug trace. Despite the trace
is not helpful, we can check the return value for the get_temp() ops in the
call site and show the message in this place.

With this set of changes, the thermal_zone_device is almost self-encapsulated.
As usual, the acpi driver needs a more complex changes, so that will come in a
separate series along with the structure moved the private core headers.

Changelog:
	- V4:
	   - Collected more tags
	   - Fixed a typo therma_zone_device_priv() for db8500
	   - Remove traces patch [20/20] to be submitted separetely
	- V3:
	   - Split the first patch into three to reduce the number of
	     recipients per change
	   - Collected more tags
	   - Added missing changes for ->devdata in some drivers
	   - Added a 'type' accessor
	   - Replaced the 'type' to 'id' changes by the 'type' accessor
	   - Used the 'type' accessor in the drivers
	- V2:
	   - Collected tags
	   - Added missing changes for ->devdata for the tsens driver
	   - Renamed thermal_zone_device_get_data() to thermal_zone_priv()
	   - Added stubs when CONFIG_THERMAL is not set
	   - Dropped hwmon change where we remove the tz->lock usage

Thank you all for your comments
