this interface.

All these controls needs admin privilege to update.
``enable`` (RW)
1 for enable, 0 for disable. Shows the current enable status of
platform temperature control feature. User space can enable/disable
hardware controls.
``temperature_target`` (RW)
Update a new temperature target in milli degree celsius for hardware to
use for the temperature control.
Given that this is platform temperature control, it is expected that a
single user-level manager owns and manages the controls. If multiple
user-level software applications attempt to write different targets, it
can lead to unexpected behavior.
