Subject: [PATCH V2] drm/amdgpu: move smu_debug_mask to a more proper place

As the smu_context will be invisible from outside(of power). Also, the smu_debug_mask can be shared around all power code instead of some specific framework(swSMU) only.

v1->v2:
  - drop non-necessary intermediate adev(Guchun)
  - move smu_debug_mask inside struct amdgpu_pm(Lijo)
