b7563ec7d9 drm/i915: Report steering details in debugfs 
Add a new 'steering' node in each gt's debugfs directory that tells
whether we're using explicit steering for various types of MCR ranges
and, if so, what MMIO ranges it applies to.

We're going to be transitioning away from implicit steering, even for
slice/dss steering soon, so the information reported here will become
increasingly valuable once that happens.

v2:
 - Adding missing 'static' on intel_steering_types[]  (Jose, sparse)
v3:
 - "static const char *" -> "static const char * const" (sparse)

82a149a62b 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.

390cf1b28b drm/i915/pxp: add pxp debugfs 
2 debugfs files, one to query the current status of the pxp session and one
to trigger an invalidation for testing.

v2: rename debugfs, fix date (Alan)

v12: rebased to latest drm-tip (rename of files/structs from
     debugfs_gt to intel_debugfs_gt caused compiler errors).

23f6a829a6 drm/i915: rename debugfs_gt_pm files 
We shouldn't be using debugfs_ namespace for this functionality. Rename
debugfs_gt_pm.[ch] to intel_gt_pm_debugfs.[ch] and then make
functions, defines and structs follow suit.

While at it and since we are renaming the header, sort the includes
alphabetically.
