drm/radeon/kms: add dpm support for sumo asics (v2)
This adds dpm support for sumo asics. This includes: - clockgating - powergating - dynamic engine clock scaling - dynamic voltage scaling set radeon.dpm=1 to enable it. v2: fix indention Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Jerome Glisse <jglisse@redhat.com>
