Revert "drm/amd/pm: keep the BACO feature enabled for suspend"

This reverts commit eaa090538e8d21801c6d5f94590c3799e6a528b5.

Commit ebc002e3ee78 ("drm/amdgpu: don't use BACO for reset in S3")
stops using BACO for reset during suspend, so it's no longer
necessary to leave BACO enabled during suspend.  This fixes
resume from suspend on the navy flounder dGPU in the ASUS ROG
Strix G513QY.
