drm/amd/display: Update V_UPDATE whenever VSTARTUP changes 



[Why]
If VSTARTUP changes due to bandwidth requirements, we must
recalculate and update VLINE2 as well for proper flip reporting.

[How]
After all calls to program_global_sync which reconfigures
VSTARTUP, also make sure to update V_UPDATE (i.e. VLINE2 on DCNx).
