[Why]
DCN32 uses ABM register definitions in dcn32_resource.h, remove
duplicate from dce_abm.h to avoid confusion.

[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.

[Why]
These functions can be called from high IRQ levels and the OS will hang
if it tries to use a usleep_highres or a msleep.

[How]
Replace the fsleep with a udelay.

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

<content type='text'>
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 &amp; HOW]
IGT's kms_hdmi_inject (subtest inject_audio) triggers a warning message
from dce_aud_az_configure. This can be fixed by checking Virtual signal
that does not need to configure AZ audio since it does not have any.
