drm/amd/display: Check for dmcu initialization before calling dmcu

Browse source

[Why]
DMCU firmware is not required - the system is expected to run
fine without it.  Therefore, wherever dmcu functions could be
called, dmcu initialization shoudl be checked

[How]
Use the helpful hook dmcu_funcs->is_dmcu_initialized
