[PATCH mlx5-next 03/11] net/mlx5_core: Clean driver version and name

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@nvidia.com>

Remove exposed driver version as it was done in other drivers,
so module version will work correctly by displaying the kernel
version for which it is compiled.

And move mlx5_core module name to general include, so auxiliary drivers
will be able to use it as a basis for a name in their device ID tables.
