However we are passing around the crtc we think that the plane is supposed to be using rather than the crtc it is currently using. That doesn't work all that well because we may have to do vblank waits etc. and the other pipe might not even be enabled here. So let's pass the plane's current crtc to intel_plane_disable_noatomic() so that it can its job correctly. To do that semi-cleanly we also have to change the plane readout to record the plane's visibility into the bitmasks of the crtc where the plane is currently enabled rather than to the crtc we want to use for the plane. One caveat here is that our active_planes bitmask will get confused if both planes are enabled on the same pipe. Fortunately we can use plane_mask to reconstruct active_planes sufficiently since plane_mask still has the same meaning (is the plane visible?) during readout. We also have to do the same during the initial plane readout as the second plane could clear the active_planes bit the first plane had already set.
