Fix a warning that was reported by the kernel test robot:
In file included from ../include/math-emu/soft-fp.h:27,
from ../arch/sh/math-emu/math.c:22:
../arch/sh/include/asm/sfp-machine.h:17: warning: "__BYTE_ORDER" redefined
17 | #define __BYTE_ORDER __BIG_ENDIAN
In file included from ../arch/sh/math-emu/math.c:21:
../arch/sh/math-emu/sfp-util.h:71: note: this is the location of the previous definition
71 | #define __BYTE_ORDER __LITTLE_ENDIAN
Fixes: b929926f01 ("sh: define __BIG_ENDIAN for math-emu")
