[PATCH 5/9] drm/i915: print object bindings in debugfs

[Rodrigo Vivi <rodrigo.vivi@gmail.com>]

From: Daniel Vetter <daniel.vetter@ffwll.ch>

This is useful when we only have aliasing ppgtt and want to figure out
what exactly is accesssible and what not. Paulo can somehow overwrite
the fbcon framebuffer with the blitter on his hsw machine ...

v2: Actually make it compile.
