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.
