drm/amd/display: add default clocks if not able to fetch them

Browse Source 
commit 946621691f9919c263b4679b77f81f06019d3636 upstream.

dm_pp_get_clock_levels_by_type needs to add the default clocks
to the powerplay case as well.  This was accidently dropped.

Fixes: b3ea88fef321de ("drm/amd/powerplay: add get_clock_by_type interface for display")
