Jacob Keller 41b145024c mlx4: fix "initializer element not constant" compiler error 
A recent commit e893768179 ("devlink: prepare to support region
operations") used the region_cr_space_str and region_fw_health_str
variables as initializers for the devlink_region_ops structures.

This can result in compiler errors:
drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: error: initializer
element is not constant
   .name = region_cr_space_str,
           ^
drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: note: (near
initialization for ‘region_cr_space_ops.name’)
drivers/net/ethernet/mellanox//mlx4/crdump.c:50:10: error: initializer
element is not constant
   .name = region_fw_health_str,

The variables were made to be "const char * const", indicating that both
the pointer and data were constant. This was enough to resolve this on
recent GCC (gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1) for this author).

Unfortunately this is not enough for older compilers to realize that the
variable can be treated as a constant expression.

Fix this by introducing macros for the string and use those instead of
the variable name in the region ops structures.

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.
