[PATCH v4 0/9] 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 in this commit:
. Prepare for capture registers
    There is a bo create at guc ads init time, that is very early
    and engine 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.
