Rename the thermal documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Temperature management

In order to protect the GPU from overheating, Nouveau supports 4 configurable
temperature thresholds:

- * Downclock: The GPU will be downclocked to reduce its power dissipation;
- * Critical: The GPU is put on hold to further lower power dissipation;

-1.4.1 struct thermal_bind_params
+---------------------------
+
+ ::
+
+ struct thermal_bind_params
+
This structure defines the following parameters that are used to bind
a zone with a cooling device for a particular trip point.
- .cdev: The cooling device pointer
- .weight: The 'influence' of a particular cooling device on this
- zone. This is relative to the rest of the cooling
- devices. For example, if all cooling devices have a
- weight of 1, then they all contribute the same. You can
- use percentages if you want, but it's not mandatory. A
- weight of 0 means that this cooling device doesn't
- contribute to the cooling of this zone unless all cooling
- devices have a weight of 0. If all weights are 0, then
- they all contribute the same.
- .trip_mask:This is a bit mask that gives the binding relation between
- this thermal zone and cdev, for a particular trip point.
- If nth bit is set, then the cdev and thermal zone are bound
- for trip point n.
- .binding_limits: This is an array of cooling state limits. Must have
- exactly 2 * thermal_zone.number_of_trip_points. It is an
- array consisting of tuples <lower-state upper-state> of
- state limits. Each trip will be associated with one state
- limit tuple when binding. A NULL pointer means
- <THERMAL_NO_LIMITS THERMAL_NO_LIMITS> on all trips.
- These limits are used when binding a cdev to a trip point.

Rename the perf documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
