drm/amd/display: Fix Silence warnings

Also affects: freesync, hdcp, info_packet, power

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

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

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