parisc: math-emu: Avoid "fmt" macro collision

Browse Source 
The printk "fmt" macro was colliding. Rename like the others with a
"bits" suffix. Fixes a build failure:

arch/parisc/math-emu/decode_exc.c: In function 'decode_fpu':
arch/parisc/math-emu/decode_exc.c:49:14: error: expected identifier before numeric constant
   49 | #define fmt  11 /* bits 19 & 20 */
      |              ^~
./include/linux/printk.h:379:6: note: in expansion of macro 'fmt'
  379 |     .fmt = __builtin_constant_p(_fmt) ? (_fmt) : NULL, \

      |   ^~~~~~
