drm/amd/display: Refactor HWSS into component folder
[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.
