The following changes are reworking entirely the thermal device tree
initialization. The old version is kept until the different drivers
using it are converted to the new API.
The old approach creates the different actors independently. This
approach is the source of the code duplication in the thermal OF
because a thermal zone is created but a sensor is registered
after. The thermal zones are created unconditionnaly with a fake
sensor at init time, thus forcing to provide fake ops and store all
the thermal zone related information in duplicated structures. Then
the sensor is initialized and the code looks up the thermal zone name
using the device tree. Then the sensor is associated to the thermal
zone, and the sensor specific ops are called with a second level of
indirection from the thermal zone ops.
When a sensor is removed (with a module unload), the thermal zone
stays there with the fake sensor.
The cooling device associated with a thermal zone and a trip point is
stored in a list, again duplicating information, using the node name
of the device tree to match afterwards the cooling devices.
The new approach is simpler, it creates a thermal zone when the sensor
is registered and destroys it when the sensor is removed. All the
matching between the cooling device, trip points and thermal zones are
done using the device tree, as well as bindings. The ops are no longer
specific but uses the generic ones provided by the thermal framework.
When the old code won't have any users, it can be removed and the
remaining thermal OF code will be much simpler.

This transient change allows to use old and new OF together until all
the drivers are converted to use the new OF API.
This will go away when the old OF code will be removed.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.
sata_ahci_read_temperature() is used by sata_ahci_show_temp() also.
So in order to change the function prototype for the get_temp ops which
does not take a void* but a thermal_zone_device* structure, this
function wraps the call.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

Given the trip points can be set in the thermal zone structure, there
is no need of a specific OF function to do that. Move the code in the
place where it is generic, in the sysfs set_trip_temp storing
function.
