This changes not needed for debugfs control of drrs. As of now debugfs provides the crtc index in the active crtc list. Instead providing the crtc id might help to identify the crtc, that the debuginfo is associated to.
Anyway as there is no usecase that need this change, I will remove it from this patch.
