Userspace tools are not aware of how to convert the enums provided by
the tracepoints to their corresponding strings.
Adding TRACE_DEFINE_ENUM() macros allows to make the enums available
to userspace to let the tools know what those enum values represent.
In particular, for thermal zone trip types what we obtained before was
something like:
kworker/1:1-460 [001] 320.372732: thermal_zone_trip: thermal_zone=soc
id=0 trip=1 trip_type=1
Unfortunately, userspace tools do not know how to convert enum values to
strings and as a consequence they can only forward the enum value to the
output. By using TRACE_DEFINE_ENUM() macros for thermal traces we get the
following trace line:
kworker/1:1-460 [001] 320.372732: thermal_zone_trip: thermal_zone=soc
id=0 trip=1 trip_type=PASSIVE
Userspace tools are now able to better understand the meaning of the trip_type
and provide the user with more readable information.

Tracing is useful for debugging and performance tuning. Add similar
traces to what's present in the cpu cooling device.

Create a new event to trace when the temperature is above a trip
point. Use the trace-point when handling non-critical and critical
trip pionts.

Introduce and use an event to trace when a cooling device's state is
updated. This is useful to follow the effect of governor decisions on
cooling devices.

Create a new event to trace the temperature of a thermal zone. Using
this event trace the temperature changes of the thermal zone every-time
it is updated.
