Subject: [PATCH v7 0/4] bitfield initial refactor within nova-core

These patches implement the initial refactoring and few improvements to the
register and bitfield macros. Rebased on drm-rust-next.

Main difference from the previous series [1] is dropped the moving out of
nova-core pending BoundedInt changes:
https://lore.kernel.org/all/20251003154748.1687160-1-joelagnelf@nvidia.com/
Other than that, added tags, resolved conflict with kernel::fmt changes and
rebased on drm-rust-next.

Alexandre Courbot (1):

Joel Fernandes (3):
  gpu: nova-core: bitfield: Move bitfield-specific code from register!
    into new macro
  gpu: nova-core: bitfield: Add support for different storage widths
  gpu: nova-core: bitfield: Add support for custom visiblity
