Aurabindo Pillai b61a06eca1 drm/amd/display: trigger timing sync only if TG is running
commit 6066aaf74f upstream

[Why&How]
If the timing generator isnt running, it does not make sense to trigger
a sync on the corresponding OTG. Check this condition before starting.
Otherwise, this will cause error like:

*ERROR* GSL: Timeout on reset trigger!
