[Intel-gfx] [PATCH v2 4/4] drm/i915/display: Remove MBUS joining invalid TODOs

[José Roberto de Souza]

skl_compute_ddb() will for a modeset in all pipes when MBUS joining
changes between states, so all pipes will be disabled, have all
MBUS related registers updated and then each pipe enabled.
So no vblank syncronization is necessary and here droping those TODOs.
