Subject: [RFC PATCH 2/2] net/mlx5: Kconfig: Use "uses" instead of "imply"

mlx5 uses the imply keyword to force weak dependencies on the implied
modules, to make sure they are always reachable by mlx5.

"imply" doesn't work this way any more, and it was wrong to use it in
first place.

The right solution is to use: "depends on symbol || !symbol", which is
exactly what the uses keyword is there for.

Use the new "uses" keyword to replace all mlx5 implied dependencies.
