drm/i915/gt: move remaining debugfs interfaces into gt
The following interfaces:
i915_wedged
i915_forcewake_user
are dependent on gt values. Put them inside gt/ and drop the
"i915_" prefix name. This would be the new structure:
dri/0/gt
|
+-- forcewake_user
|
\-- reset
For backwards compatibility with existing igt (and the slight
semantic difference between operating on the i915 abi entry
points and the deep gt info):
dri/0
|
+-- i915_wedged
|
\-- i915_forcewake_user
remain at the top level.
