This is v2 for a previous patch series being discussed at
https://lore.kernel.org/dri-devel/20220517174216.381287-1-adrian.larumbe@collabora.com/.

Mesa MR under review can be found at:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14034

Changes with respect to v1 of the same patch:

 - Change the list of dumped registers to those of greatest debugging value.
 - Fix bug where an invalid bomap header wouldn't be dumped
 - Changed the way that a decision is made whether to dump a BOMAP header so
 that no compiler warning supression has to be done.
 - Changed magic number for header fields to something more representative.
 - Changed the dump header format to a union whose members are the different
   header types.
