drm/amdgpu/powerplay: add a new interface to set the mp1 state
This is required for certain cases such as various GPU resets (mode1, mode2), BACO, shutdown, unload, etc. to put the SMU into the appropriate state for when the hw is re-initialized. Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
