thermal: introduce device tree parser
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.
