[[Only compile tested] 20/21] drm/i915: Add debugfs dumping for bigjoiner.

[Maarten Lankhorst]

It's useful to know what the actual clipped state is, rather than
the unclipped crtc properties.

This is useful when a plane is spread across 2 crtc's, where the
slave crtc has no own plane properties but derives its clipped
values from the master crtc.
