is_timing_changed() is actually meant to be a global symbol, but needs
a proper name and prototype, while the other two can just be made static.
Fixes: 54c7b715b5ef ("drm/amd/display: Add DSC Support for Synaptics Cascaded MST Hub")
Fixes: 17ce8a6907f7 ("drm/amd/display: Add dsc pre-validation in atomic check")
Fixes: 8f0d304d21b3 ("drm/amd/display: Do not commit pipe when updating DRR")

It seems like, only the changes for is_timing_changed() are in this patch.
