[PATCH v7 0/4] drm/xe: Report GT TDR and VM rebind faults using SIGID

[Arvind Yadav <arvind.yadav@intel.com>]

This series is a small follow-up on top of the structured SIGID error
logging infrastructure series:

https://patchwork.freedesktop.org/series/171022/

That series adds SIGID-based error reporting and the xe_log_*() helpers.
This series converts selected GuC submission, SVM page-fault and GT reset
error paths to that logging path.

The VM rebind conversion from earlier revisions remains dropped.

v7:
 - Updated the GUCSUBMIT commit message.
 - Updated GuC submission wording.
 - Added a GRDOM_RESET_TIMEOUT_MS constant for GT reset timeout.

v6:
 - Moved GUCSUBMIT from DRIVER_FIRMWARE to DRIVER, since GuC submit
   is a driver submission component and not a firmware component.
   (Michal)
 - Updated the log message to print class/instance as %u:%u and
   reason as %#x. (Michal)

v5:
 - Dropped the GuC CGP protocol SIGID conversion, since malformed G2H
   handler errors are already reported by the CT layer after -EPROTO.
 - Added a GUCSUBMIT component mapped to XE_SIGID_GT_TDR and used it for
   the GuC submit reset failure.
 - Dropped "request" from the GuC submit reset failure message.
 - Kept the GT patch limited to the reset failure path.
 - Dropped GT PM-flow SIGID conversions for now, since the correct
   component/SIGID mapping needs agreement.
 - Improved the GT reset failure message to describe that full graphics
   reset did not complete.

v4:
 - Clarified that the GT component maps to XE_SIGID_GT_TDR and -EIO is
   only the errno value.
 - Split GuC CGP protocol error conversions into a separate patch.
 - Added terminal SVM page-fault allocation failures as MEM_FAULT reports.
 - Converted GT reset and power-flow failures to GT_TDR reports.
 - Kept the VM rebind conversion dropped.

v3:
 - Split GuC and VM changes into separate patches.
 - Dropped GuC job-timeout warning conversions to avoid changing warning
   logs into error-level SIGID reports.

v2:
 - Rebased on the latest structured SIGID logging series.
 - Switched from the old xe_ras_log_*() helpers to the new xe_log_*()
   helpers.
