We were previsously updating MBUS/DBOX/DBUF CTL registers incorrectly, doing it in a single place, even though BSpec instructs to do it before or after DDB reallocation depending on the scenario, also we missed a vblank wait in one scenario, which forced us to use a full modeset in all cases when MBUS join state needed to be changed, preventing fastset to be done in certain cases. This patch series attempts to fix that.
