[PATCH v10 0/5] drm/xe/guc: Add GuC based register capture for error capture

[Zhanjun Dong <zhanjun.dong@intel.com>]

Port GuC based register capture for error capture from i915 to Xe.

There are 3 parts inside:
. Prepare for capture registers
    There is a bo create at guc ads init time, that is very early
    and engi  ne map is not ready, make it hard to calculate the
    capture buffer size, new function created for worst case size
    caluation. Other than that, this part basically follows the i915
    design.
. Process capture notification message
    Basically follows i915 design
. Sysfs command process.
    Xe switched to devcoredump, adopted command line process with
    captured node list.

Changes from prior revs:
 v10:-  Resync with updated job timed out follow
        Add pre-capture by read from hw engine if GuC capture data is not
        ready, the pre-captured data will be refereshed if GuC capture is
        ready at later time.
        Add xe_guc_capture_is_ready_for to check if GuC capture is ready
        for a job.
        Re-orgnize some header files to xe abi folder
        Reduce some meesage level from warn/info to debug
        Remove duplicated enum of GuC log type.
  v9:-  Merged snapshot register list into capture register lists
        Optimized devcoredump timing to take snapshot after guc reset
        Add global and engine class registers into capture list
        Fixed bug of incorrect matching guc class id with guc capture class id
  v8:-  Reorgnize the order of patches
        Change the capture size check from worst min size to worst size
        Replace the kernel alloc with drm managed alloc
        Replace the memcpy with xe_map_memcpy_from
        Free GuC capture outlist as part of xe_devcoredump_free
  v7:-  Kconfig CONFIG_DRM_XE_CAPTURE_ERROR removed
  v6:-  Change hardcoded register snapshot fill to follow mapping tables
        When capture is empty, take snapshot from engine
  v5:-  Split dss helper code out as an standalone patch
        Remove old platform registers definition.
        Split register map table to 32 and 64bit each
  v4:-  Move register map table to xe_hw_engine.c
  v3:-  Remove condition compilation in code
  v2:-  Split into multiple chunks
