msm: thermal: Add support for partial goods CPU

Add support to thermal driver to handle partial
goods.

In this case, it is possible that some physical
CPUs may not be brought online and it can be
decided runtime. This behavior changes the physical
CPU to logical CPU numbering dynamic.

Thermal driver should be capable to map the
temperature sensor with the correct logical CPU number.
This is achieved by creating different mitigation
profiles and associating each physical CPU to one
profile using device tree phandle. Thus thermal driver
identifies the thermal profile associated with the
logical CPU and then determines the mitigation
information. The mitigation profile has a phandle to the
temperature sensor and devicetree properties to
enable or disable various type of mitigation.
A single device can have multiple sensors mapped in
array of phandles or even multiple sensors mapping
to a single sensor.
