With [1] dpu core revision was dropped in favor of using the

This approach works well however also necessitates adding catalog
entries for small register level details as dpu capabilities and/or
features bloating the catalog unnecessarily. Examples include but
are not limited to data_compress, interrupt register set, widebus etc.
Generic note: this description can be moved to the cover letter, it
covers the series intent.
I kept it here as I didnt really have a cover letter but I can add one
and move this there.
Introduce the dpu core revision back as an entry to the catalog so that
we can just use dpu revision checks and enable those bits which
should be enabled unconditionally and not controlled by a catalog
and also simplify the changes to do something like:
if (dpu_core_revision > xxxxx && dpu_core_revision < xxxxx)
enable the bit;
Since dpu's major and minor versions are now separate fields, lets
drop all the DPU_HW_VER macros.

Please use `commit aabbcc ("do this and that")' in the commit messages.
Ack.
changes in v3:
- drop DPU step version as features are not changing across steps
- add core_major_version / core_minor_version to avoid conflicts
- update the commit text to drop references to the dpu macros
