It is only read-from, so make it const. In order to be able to do this, constify all places where mxc_jpeg_fmt is used, in function arguments, return values and pointers. On top of that, make the name a pointer to const char. On aarch64, this shrinks object code size with 550 bytes with gcc 11.1.0, and almost 2kB with clang 12.0.0.

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.
