Subject: [PATCH] drm/amdgpu: don't enable baco on boco platforms in runpm
Git-commit: 202ead5a3c589b0594a75cb99f080174f6851fed
Patch-mainline: v5.14-rc6
References: git-fixes

If the platform uses BOCO, don't use BACO in runtime suspend.
We could end up executing the BACO path if the platform supports
both.
