drm/amd/display: Fix scratch registers offsets for DCN351

[Why]
Different platforms use different NBIO header files,
causing display code to use differnt offset and read
wrong accelerated status.

[How]
- Unified NBIO offset header file across platform.
- Correct scratch registers offsets to proper locations.
