[PATCH v2 1/3] drm/xe/guc: Explicitly name each chunk of GuC log data in a dump

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

A mesa devcoredump decoding tool does not cope with line wrapped
ASCII85 data. The GuC log is saved and printed in chunks. Only the
first chunk was named, thus subsequent chunks were effectively line
wrapped data. So add names to all the chunks instead.

v2: Fix size of name variable.
