drm/amd: Only run s3 or s0ix if system is configured properly
This will cause misconfigured systems to not run the GPU suspend routines. * In APUs that are properly configured system will go into s2idle. * In APUs that are intended to be S3 but user selects s2idle the GPU will stay fully powered for the suspend. * In APUs that are intended to be s2idle and system misconfigured the GPU will stay fully powered for the suspend. * In systems that are intended to be s2idle, but AMD dGPU is also present, the dGPU will go through S3 Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
