This patch removes the following checks from validation
of modify field action:
- rejection of ADD operation,
- offsets should be aligned to 4 bytes.
These limitations were removed in
commit 0f4aa72b99 ("net/mlx5: support flow modify field with HWS"),
but non-HWS validation was not updated.
Notes about these limitations are removed from mlx5 PMD docs.
On top of that, the current offsetting behavior in modify field action
is clarified in the mlx5 docs.
