drm/amdgpu: complete gfxoff allow signal during suspend without delay
commit 4b31b92b143f7d209f3d494c56d4c4673e9fc53d upstream. change guarantees that gfxoff is allowed before moving further in s2idle sequence to add more reliablity about gfxoff in amdgpu IP's suspend flow Signed-off-by: Harsh Jain <harsh.jain@amd.com> Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: "Limonciello, Mario" <Mario.Limonciello@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
