From: Yongqiang Sun <yongqiang.sun@xxxxxxx> [Why] System is unable to enter S0i3 due to DISPLAY_OFF_MASK not asserted in SMU. [How] Optimized bandwidth should be called paired and to resolve unplug display underflow issue, optimize bandwidth after commit streams is moved to next page flip, in case of S0i3, there is a change for no flip coming causing display count is 1 in SMU side. Add optimize bandwidth after commit stream.
