[PATCH mlx5-next v4 2/4] net/mlx5: Add dynamic MSI-X capabilities bits

From: Leon Romanovsky <leonro@nvidia.com>

These new fields declare the number of MSI-X vectors that is
possible to allocate on the VF through PF configuration.

Value must be in range defined by min_dynamic_vf_msix_table_size
and max_dynamic_vf_msix_table_size.

The driver should continue to query its MSI-X table through PCI
configuration header.
