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

./include/linux/printk.h:417:3: note: in expansion of macro '__printk_index_emit'
417 | __printk_index_emit(_fmt, NULL, NULL); \
