drm/amd/display: Fixed Silence complier warnings in dc

[Why]
Resolve compiler warnings by marking unused parameters explicitly.

[How]
In .c and .h function definitions, keep parameter names
in signatures and add a line with `(void)param;` in function body

Preserved function signatures and avoids breaking code paths that
may reference the parameter under conditional compilation.
