[PATCH 09/15] drm/amd/display: Add missing post flip calls

[Ray Wu]

From: Dillon Varone <dillon.var...@amd.com>

[WHY&HOW]
dc_post_update_surfaces_to_stream needs to be called after a full update
completes in order to optimize clocks and watermarks for power. Add
missing calls before idle entry is requested to ensure optimal power.
