arm64: dts: rockchip: update thermal config and add gpu's parameters for rk3368

Browse Source 
add both static and dynamic power coefficient for gpu
module, and add gpu as a cooling device in the thermal zone.
rename the thermal zone's config and make it more readable.
update temperature pooling interval and make the temperature
control more effective.
