v3 of https://patchwork.freedesktop.org/series/119766/
Changes from v2:
- Do not rmw if (clr | set) covers all bits
- Add patch to make sure the set bits are also checked on
wa_*_clr_set() when clr is not a superset.
Tested on DG2 with intel_reg reading 0xb158 with a busy render engine.
Now it's not losing the upper bit anymore.

Thanks a lot for fixing this, Lucas!
Thanks for the detailed review and help fixing this.
All patches pushed to drm-intel-gt-next branch. Later this week I will
work on getting the important fix backported to the relevant stable
trees.
