Extend eswitch API with rate limiting groups:

- Define new struct mlx5_esw_rate_group that is used to hold all
  internal group data.

- Implement functions that allow creation, destruction and cleanup of
  groups.

- Assign all vports to internal unlimited zero group by default.

This commit lays the groundwork for group rate limiting by implementing
devlink_ops->rate_node_{new|del}() callbacks to support creating and
deleting groups through devlink rate node objects. APIs that allows
setting rates and adding/removing members are implemented in following
patches.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
