net/mlx5e: Enable lanes configuration when auto-negotiation is off

Browse source 
Currently, when auto-negotiation is disabled, the driver retrieves
the speed and converts it into all link modes that correspond to
that speed. With this patch, we add the ability to set the number
of lanes, so that the combination of speed and lanes corresponds to
exactly one specific link mode for the extended bit map.

For the legacy bit map the driver sets all link modes correspond to
speed and lanes.

This change provides users with the option to set a specific link
mode, rather than enabling all link modes associated with a given
speed when auto-negotiation is off.
