drm/amd/display: trigger timing sync only if TG is running
[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!
Fixes: dc55b106ad477c ("drm/amd/display: Disable phantom OTG after enable for plane disable")
