[Why] Our old logic: if pageflip, update freesync and plane address. Otherwise, update everything. This over-updated on non-pageflip cases, and it failed to update if pageflip and non-pageflip changes occurred on the same commit [How] Update flip_addrs on pageflips. Update scaling_info when it changes. Update color fields on color changes. Updates plane_info always because we don't have a good way of knowing when it needs to be updated. Unfortunately, this means that every stream commit involves two calls into DC. In particular, on pageflips there is a second, pointless update that changes nothing but costs several microseconds (about a 50% increase in time taken). The update is fast, but there are comparisons and some useless programming. Leave TODOs indicating dissatisfaction.
