drm/amdgpu/vangogh: don't check for dpm in is_dpm_running when in suspend

BugLink: https://bugs.launchpad.net/bugs/1923069
commit 6951c3e4a260f65a16433833d2511e8796dc8625 upstream.

Do the same thing we do for Renoir.  We can check, but since
the sbios has started DPM, it will always return true which
causes the driver to skip some of the SMU init when it shouldn't.
