If an MST stream is modeset, its state must be checked along all the other streams on the same MST link, for instance to resolve a BW overallocation of a non-sink MST port or to make sure that the FEC is enabled/disabled the same way for all these streams. To prepare for that this patch adds all the stream CRTCs to the atomic state and marks them for modeset similarly to tgl+ platforms. (If the state computation doesn't change the state the CRTC is switched back to fastset mode.)
