drm/amdgpu/gfx9: use amdgpu_gfx_off_ctrl_immediate() for PG

Use amdgpu_gfx_off_ctrl_immediate() when powergating.
There's no need for the delay in gfx off allow.  The
powergating is dynamically disabled/enabled as for
RV/PCO on compute queues and allowing gfx off again as
soon the job is submitted improves power savings.
