Introduce an optional property called, sustainable-power, which
represents the power (in mW) which the thermal zone can safely
dissipate.
If provided the property is parsed and associated with the thermal
zone via the thermal zone parameters.

There are various issues with the examples in this documentation, some
of the DT labels are invalid and one of the macro THERMAL_NO_LIMITS
referenced is not available as well.
This patch attempts to fix such errors in the documentation.

This patch introduces a device tree bindings for
describing the hardware thermal behavior and limits.
Also a parser to read and interpret the data and feed
it in the thermal framework is presented.
This patch introduces a thermal data parser for device
tree. The parsed data is used to build thermal zones
and thermal binding parameters. The output data
can then be used to deploy thermal policies.
This patch adds also documentation regarding this
API and how to define tree nodes to use
this infrastructure.
Note that, in order to be able to have control
on the sensor registration on the DT thermal zone,
it was required to allow changing the thermal zone
.get_temp callback. For this reason, this patch
also removes the 'const' modifier from the .ops
field of thermal zone devices.
