Christophe JAILLET bec2a32145 mlxsw: spectrum_acl_flex_keys: Constify struct mlxsw_afk_element_inst
'struct mlxsw_afk_element_inst' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increases overall security.

Update a few functions and struct mlxsw_afk_block accordingly.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   4278	   4032	      0	   8310	   2076	drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_flex_keys.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   7934	    352	      0	   8286	   205e	drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_flex_keys.o

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 reStructuredText 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.
