drm/i915: Added debug state dump facilities to scheduler

When debugging batch buffer submission issues, it is useful to be able
to see what the current state of the scheduler is. This change adds
functions for decoding the internal scheduler state and reporting it.

v3: Updated a debug message with the new state_str() function.

v4: Wrapped some long lines to keep the style checker happy. Removed
the fence/sync code as that will now be part of a separate patch series.

v5: Removed forward declarations and white space. Added documentation.

Also squashed in later patch to add seqno information from the start.
It was only being added in a separate patch due to historical reasons
which have since gone away.

v6: Updated to newer nightly (lots of ring -> engine renaming).

Added 'for_each_scheduler_node()' helper macro. Updated to use
'to_i915()' instead of dev_private. Converted all enum labels to
uppercase. Moved the enum to string conversion function to debugfs.c
rather than scheduler.c [review feedback from Joonas Lahtinen]
