Subject: [PATCH] drm/amd/powerplay: Enable/Disable NBPSTATE
[Why]
There is a race that between drm_crtc_commit_hw_done and
drm_atomic_helper_wait_for_flip where the possibilty exist for the

[How]

Export this interface for the AMDGPU_FW_LOAD_SMU type.
This interface only be supported on VI. and gfx/sdma's
firmware will be loaded together by smu.
so in AMDGPU_FW_LOAD_SMU mode, the gfx and sdma ip
can't be disabled by module parameter.
Split the smu7/8_start_smu function into two functions
