[Quan, Evan] This is needed by amdgpu_hwmon_show_power_label() from amdgpu_pm.c. 
So, it has to be put into some place which can be accessed from outside(of power).
Then kgd_pp_interface.h is the right place.

[Quan, Evan] "smu" is updated as dynamically allocated. We need to find a place to get it freed.
As did in powerplay framework, ->late_fini is the right place.

[Quan, Evan] This was moved from amdgpu_dpm.c to here (amdgpu_smu.c).
As smu_context is now an internal data structure for swsmu framework.
Then the accessing for smu->ppt_funcs should be launched from amdgpu_smu.c.
