[ Impact ]

While compile on AMD64 platform, the following error happens:

drivers/net/ethernet/mellanox/mlx5/core/health.c: In function ‘mlx5_health_get_crr’:
drivers/net/ethernet/mellanox/mlx5/core/health.c:101:33: error: ‘MLX5_CRR_BIT_OFFSET’ undeclared (first use in this function); did you mean ‘MLX5_RFR_BIT_OFFSET’?

  102 | }
      | ^

[ Fix ]

To fix this, the suggestion has been to import the following patchset

https://lore.kernel.org/all/20250219085808.349923-1-tariqt@nvidia.com/
* cherry-picked 80df31f384b4146a62a01b3d4beb376cc7b9a89e from upstream
* cherry-picked 531ca2b9a215d072ffb4b1ff760a73f5e80c9c46 from upstream

[ Test plan ]

Compile test only

[ Potential regressions ]

The patch introduces a new macro and the scope is quite small, no regressions are expected.
