Subject: thermal: add available policies sysfs attribute

The Linux thermal framework support to change thermal governor
policy in userspace, but it can't show what available policies
supported.

This patch adds available_policies attribute to the thermal
framework, it can list the thermal governors which can be
used for a particular zone. This attribute is read only.

Subject: thermal: consistently use int for temperatures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The thermal code uses int, long and unsigned long for temperatures
in different places.

Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.

'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.

Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

Subject: thermal: remove unnecessary call to thermal_zone_device_set_polling

When the thermal zone has no get_temp callback then thermal_zone_device_register()
calls thermal_zone_device_set_polling() with a polling delay of 0. This
only cancels the poll_queue. Since the poll_queue hasn't been scheduled this
is a no-op. Remove it.
