[PATCH v6 0/8] drm/xe/guc: Add GuC based register capture for error capture

[Zhanjun Dong]

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:
  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
