As RK3399 had used the Power allocator thermal governor by default,
enabled this to manage thermals by dynamically allocating and limiting
power to devices.
Also, this patch supported the dynamic-power-coefficient/sustainable_power
and GPU's power model for needed parameters with thermal IPA.
The Thermal power allocator governor works optimatly with two passive trip
points, for the better performance we will use the trip-point0 with 70
degree above which the governor control starts operating and trip-point1
with 85 degree is the target temperature by controlling.

Changes in v2:
- foo@ will produce warnings when used without reg property.
- update the commit to explain the two passive trip points changed.
