R-car does runtime pm (that's why it's committing plane state only at the end). Therefore better to only update planes on active crtc. Note that since the helpers always add all enabled planes when doing a modeset change on a crtc we are guaranteed to update plane hw state to the latest requested state each time the crtc is enabled.
