[why] Rename hw_sequencer to hwseq. Move all hwseq files to unique folder hwss. [how] creating hwss repo in dc, and moved the dcnxx_hwseq.c and .h files into corresponding new folders inside the hwss and cleared the linkage errors by adding relative paths in the Makefile.template.

drm/amd/display: fix incorrect odm change detection logic

2023-09-26T21:00:22Z

[why] The current ODM change detection only compares first two ODM slices. If there are 4 ODM slices and the change is within the last two slices, the logic fails to detect ODM change and cause us to skip ODM programming unexpectedly. [how] Add a is ODM topology changed resource interface to check any ODM topology changes with a more generic method.

drm/amd/display: switch DC over to the new DRM logging macros

2023-09-26T21:00:21Z

For multi-GPU systems it is difficult to tell which GPU a particular message is being printed for and that is undesirable because it complicates debugging efforts. Also, the new macros allow us to enable logging for particular parts of the codebase more selectively (since we no longer need to throw everything at DRM_DEBUG_KMS()). So, for the reasons outlined above we should switch to the new macros. We can accomplish this by using the existing DC_LOGGER code to pass around the relevant `struct drm_device` which will be fed to the new macros in logger_types.h. Also, we must get rid of all instances of the DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use the DC logger there and we can simply refer to the macros directly there instead.

[Why] Triggering OTG sync before all OTG/HPO clock programming is complete causes timing sync to fail and a subsequent P-state hang.
