drm/amd/powerplay: Unify smu handle task function (v2) 

Unify power stade adjust function into smu_handle_task by the judgment
of task_id.
Move functions which have no relationship with smu version into the file
of amdgpu_smu.
Modified the function of smu_display_config_changed into two part.
Unify some similiar function.

v2: Correct the operation of upload dpm level when force dpm limit value.
