Previously, VRAM TTM resource manager debugfs entries (vram0_mm / vram1_mm)
were created globally in the XE debugfs root directory. But technically,
each tile has an associated VRAM TTM manager, which it can own.
Let's create VRAM memory manager debugfs entries directly under each tile's
debugfs directory for better alignment with the per-tile memory layout.

drm/xe/debugfs: Use scope-based runtime PM2025-11-19T19:58:58+00:00Matt Ropermatthew.d.roper@intel.com2025-11-18T16:44:06+00:00urn:sha1:423fb66fac7dbb5ee2b26c40e0d21c0ffb0d7533
Switch the debugfs code to use scope-based runtime PM where possible,
for consistency with other parts of the driver.
v2:
- Drop unnecessary 'ret' variables. (Gustavo)

We will want to use this helper function in other files.

drm/xe/debugfs: Make ggtt file per-tile2025-09-23T18:04:13+00:00Michal Wajdeczkomichal.wajdeczko@intel.com2025-09-19T16:04:29+00:00urn:sha1:126d33f6711a4e8dc9613a146932e81a988b3dc2
Due to initial lack of per-tile debugfs directories, the ggtt file
attribute was created as per-GT file. Fix that since now we have
proper per-tile directories.

drm/xe/debugfs: Move sa_info from gt to tile directory2025-09-04T10:45:09+00:00Michal Wajdeczkomichal.wajdeczko@intel.com2025-08-29T20:11:03+00:00urn:sha1:a85ead6d7f74438bc779927fe7b78b0c86addb6b
Our drm-based suballocator is implemented per-tile so it is better
to show its debug information also per-tile debugfs directory, not
under per-gt directory as it is done today.
To allow adding more per-tile attributes, prepare necessary helper
functions, like we already did for per-gt or per-uc attributes.
