commit 5095d5418193 ("drm/amd: Evict resources during PM ops prepare()
callback")
intentionally moved the eviction of resources to earlier in the suspend
process, but this introduced a subtle change that it occurs before adev->in_s0ix
or adev->in_s3 are set. This meant that APUs actually started to evict
resources at suspend time as well.
Move the s0i3/s3 setting flags into prepare() to ensure that they're set
during eviction. Drop the existing call to return 1 in this case because
the suspend() callback looks for the flags too.
