Currently, in an ACPI based system, the processor driver registers
one cooling device per processor. However, the cooling device type
is the same for each processor. For example, on a system with four
processors, the sysfs reading of each cooling device would look like:
ebv@besouro ~ $ cat /sys/class/thermal/cooling_device*/type
Processor
Processor
Processor
Processor

which turns out to fine. But, some parts of the thermal code may use
type to identify participating devices in a thermal zone. Besides,
adding notifications to user space may cause the production of messages
that may confuse the listener.

For this reason, this patch adds the processor ID cooling device type.
After this change, the cooling device listing in the same previous example
would look like this:
ebv@besouro ~ $ cat /sys/class/thermal/cooling_device*/type
Processor.0
Processor.1
Processor.2
Processor.3

allowing an easier identification of cooling device target.

Is it not going to confuse any user space scripts or similar?
