drm/i915: semaphore debugfs
Simple debugfs file to display the current state of semaphores. This is
useful if you want to see the state without hanging the GPU.
NOTE: This patch is optional to the series.
NOTE2: Like the GPU error state collection, the reads are currently
incoherent.
v2 (Rodrigo): * Iterate only on active rings.
* s/ring_buffer/engine_cs.
