Since the flip done event will be sent in the flip_done_handler, no need to add the event to the list and delay it for later.
v2: -Moved the async check above vblank_get as it was causing issues for PSR.
v3: -No need to wait for vblank to pass, as this wait was causing a 16ms delay once every few flips.
v4: -Rebased.
v5: -Rebased.
v6: -Rebased.
v7: -No need of irq disable if we are not doing vblank evade. (Ville)
