microblaze: kill incorrect __bad_xchg definition
The whole point of the __bad_xchg declaration in system.h is to give a linker error when a variable of invalid size is passed to __xchg. The out of line definition in traps.c defeats this purpose and does not any value, so remove it here. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Simek <monstr@monstr.eu>
