drm/amd/display: Add some hardware status in DTN log debugfs
[Why] For debug purpose, we need to check the following hardware status in DTN log debugfs: 1.dpp & hubp clock enable; 2.crtc blank enable; 3.link phy status; [How] Add the upper information in the amdgpu_dm_dtn_log debugfs. For CRTC blanked status, since DCN2 and greater reports it on the OPP instead of OTG, we patch it in after calling optc1_read_otg_states. Ideally, this should be done in the DCN version specific function hooks. It has been left as a TODO item.
