Subject: [PATCH 4683/5725] drm/amd/display: skip multisync for slave displays
having same timing as master
[Why]
In case if other displays has same timing as multisync master display, then
no need to force vsync on those slave displays continously instead it can be
force synced only once in program_timing_sync() function.
[How]
In enable_timing_multisync() function, skip displays which has same timing
as master display.
